Having the correct controls will help with comfort levels at a reduced cost. We are experienced and qualified in all aspects of heating and hotwater controls installation, diagnosis, and repair.
Modern gas central heating systems are safe, controllable and efficient to run but can cause confusion as they have a number of controls that you may not fully understand.

Using heating controls properly can

  • Improve the comfort of your home
  • Reduce the energy used and your fuel bills
  • Avoid the risk of condensation dampness
  • To get the best out of your system, you should follow the manufacturers instructions. If you have mislaid the instruction booklet for your systems, most manufacturers can provide a replacement.

Why have controls on a gas central heating system?

For a gas central heating and hot water system to operate efficiently it must be able to be controlled so that heating and hot water are provided at a suitable temperature, when and where you want it. Most systems include:-

  • Boiler (which can be a condensing, condensing combi, conventional or conventional combi model)
  • Hot water tank for systems without a combi boiler
  • Room thermostat
  • Radiators
  • Thermostatic radiator controls
  • Programmer
  • The Boiler

Boiler

A conventional boiler heats up the water which is circulated through radiators to provide heat. The water also circulates through a coil in the hot water tank, which in turn heats up the rest of the water in the cylinder to provide running hot water.

If your boiler is a ‘combi’ boiler then the water is heated instantaneously when the hot water taps are switched on.

The thermostat on the boiler controls the temperature of the water circulating around the system. Please refer to the manufacturer’s instructions for the optimum setting of the thermostat.

Hot Water Tank

Most hot water cylinders have a thermostat; this is recommended to be set at 55.C. To retain as much heat as possible the cylinder should have 80mm of insulation.

Radiators

Radiators are most commonly used in “wet” (uses water) central heating systems. The water is heated by the boiler and travels through the radiators, giving out heat.

Thermostatic Radiator Valves (TRVs)

Thermostatic Radiator ValveTRVs are found on radiators in rooms other than where the room thermostat (see below) is placed. The TRV senses the air temperature in the room and can be set higher in the rooms you use most and lower in rooms used least such as bedrooms. They usually have a fat valve at one end, marked with a * and numbers from 1 to 5. The * setting is to protect against frost; it will typically leave the radiator switched off unless the temperature falls below about 6°C. For a normal living room, the setting of 3 or 4 is likely to be about right; for a bedroom a cooler temperature will normally be enough. Turning the dial up when the radiator is already on will not increase the room temperature! They can also be used to turn an individual radiator on or off. Generally, one radiator should be left without a TRV and left permanently switched on, this radiator may be a bathroom towel rail (where the heat is always likely to be useful), or in the same room as the room thermostat where a TRV is not needed.

Room Thermostat

ThermostatThis is usually found in the living room or hallway and is recommended to be set at 21°C. The room thermostat will respond to the temperature in the room where it is situated. When the room is warm enough it sends a signal to the central heating pump to stop heating the radiators until the temperature drops below the set level. At this point they will come back on again.

Programmer or Timer

The programmer or timer is set to control the times when the central heating and hot water are switched on and off. The average household needs heat for about 8 hours each day. But this depends on your own personal circumstances. The majority of time clocks allow you to set two ‘on’ and ‘off’ periods during the day i.e. 8am – 10am and 4pm – 10pm.

Heating timerSo that the house is warm when you wake up, set the heating to come on approximately 30 minutes before you get up and then in the evening set the heating to turn off about 1 hour before you go to bed. This will allow the house to warm up in the morning and cool down slightly at night.

There is a variety of programmers for operating central heating (CH) and hot water (HW). The majority have the following controls:-

  • ON/CONSTANT -HW/CH is on 24 hours each day.
  • OFF – the HW/CH is completely off.
  • ONCE – the HW/CH comes on at the first “ON” time selected and turns off at the second “OFF” time selected.
  • TWICE/AUTO – the HW/CH comes on for the 2 selected time periods.
  • HOT WATER ONLY – the heating system will not operate

Replacing a hot water cylinder can be a simple task to an experienced professional.
The different types of hot water cylinders

There are two various types of hot water cylinders installed in homes across the UK. They operate to provide hot water to your home with slight differences. Each type has its advantages and disadvantages, and this part of the article describes these. The prices for replacing the hot water cylinder will differ for each type as they are fundamentally different hot water system designs.

Vented hot water cylinder

A vented hot water cylinder system consists of a cold water tank located commonly in the loft which feeds cold water to the cylinder. The cylinder is typically situated in an airing cupboard, with the cold water feed at the bottom of the tank. Heated water rises to the top of the reservoir where it is drawn off for feeding the heating system.

A vent pipe acts as an outlet for air bubbles, and steam should the cylinder overheat and also keeps the cylinder pressure at atmospheric pressure.

There are two methods of heating water with vented hot water systems, namely:

  • Direct heating – immersion heaters are fitted in the cylinder, and they solely provide the hot water.
  • Indirect heating – a coil within the hot water cylinder is fed via the central heating system and heats the water in the cylinder.

The difference between vented and unvented systems

An unvented hot water cylinder connects to the mains cold water rising mains and supplies hot water at mains pressure. Similar heating methods to the vented cylinder also apply to this type of cylinder.

The difference between vented and unvented systems is that there is no water storage tank or vent pipes. Instead, an expansion vessel is connected to the top of the cylinder. The purpose of the expansion vessel is to accommodate expanding water coming from the cylinder.

The following safety devices are necessary for unvented cylinders:

  • Primary and secondary thermostats. The main thermostat maintains the temperature of the water below 65 degrees while the secondary switches off the heater or cuts off water supply if the temperature exceeds 90 degrees Celsius.
  • At Perrin Heating we can supply and install both vented and unvented types of hot water cylinder

Powerflushing

Powerflushing is a cleansing process designed to rid the central heating system of sludge, rust and corrosive inefficiencies that accumulate over time in most heating systems.

What Is Powerflushing?

  • Powerflushing is a cleansing process designed to rid the central heating system of sludge, rust and corrosive inefficiencies that accumulate over time in most heating systems. In addition to increasing the efficiency of the heating system, the powerflush also serves to protect the main heating plant. Powerflushing should only be administered by a knowledgeable and experienced central heating expert.
  • Powerflushing is a proven solution for uneven heat distribution and for remedying the inefficiencies of the central heating system. Many homeowners are unaware that the heat circulation in their home is clogged. Powerflushing is the best way to ensure that the system is circulating properly and not adding pressure to the heating unit.
  • Powerflushing is also recommended when new systems are being installed. A new boiler replacing an older boiler is only as effective and efficient as the circulation of the existing piping. Powerflushing is a safe, relatively inexpensive process that will add warmth to the home and reduce energy expenditures at the same time.

Warning Signs That Powerflushing is Needed

There are several symptoms that indicate it is time to powerflush your central heating system.

Cold radiators – Are some radiators warm while others are cold? The reason for this is rust and sludge that has accumulated in pipes and is preventing heat from circulating to all radiators in the home.

Excessive Noise – Can you hear you boiler overworking? Do you hear air trying to fight through the sludge and rust in pipes? If your central heating system is making unusual noises, the chances are a powerflush is in order.

Discoloured Water – When you bleed your radiators and pipes are you finding the water is discoloured? That is a clear warning sign that the system is in jeopardy and in need of powerflushing. In extreme cases, you might notice that tap water is cloudy.

How Powerflushing Works

You can improve the circulation in your heating system by cleaning the pipes. You will most likely enjoy other benefits such as a quieter, more efficient operating system. Over the long-term, you will also notice that your energy expenses are decreasing.

Powerflushing is safe if administered by an experienced heating engineer likle Home Cure. The heating engineer will connect a high flow, low pressure pumping unit to the system. The most likely connection point is the circulation pump or the pump head, depending upon the system.

The engineer will add high strength cleaning chemical to the system. These include ingredients to break down sludge crust that inevitably builds on the pipes. A chemical to remove the sludge is also used along with a descaler to break down the limescale. After the initial flush, crust and rust inhibitors are added to the system.

The crust breakers and removers are acid-based cleansers. These will also rid the system of any sand that may have accumulated in the system. When the powerflush is complete, the acid will be washed thoroughly from the system.

Professional powerflushing takes can take a few hours. Most homeowners notice the difference immediately. Please feel free to get an estimate beforehand to find out about time frames and costs.

In the UK today, many residents are concerned about the cost and amount of energy used to heat their homes and businesses. Powerflushing is a great way to reduce energy expenditure, your carbon footprint and most importantly to improve the heat circulation in your home. By removing the sludge and corrosive elements from your central heating system, you are also prolonging the life of your heating plant. Replacing a boiler is one expense nobody wants to incur.

Landlords Certificates & Safety

By law, under the Gas Safety (Installation and Use) Regulations 1998, it’s your responsibility to get a Gas Safety Certificate every twelve months.

Gas Safety Certificate explained

By law, under the Gas Safety (Installation and Use) Regulations 1998, it’s your responsibility to get a Gas Safety Certificate every twelve months. You must get this from a Gas Safe Registered engineer for all pipe work, gas appliances and flues installed at your property.

If you use an agent to manage your property, you need to make sure your contract clearly states in black and white whose responsibility it is to carry out maintenance on gas appliances. You must also keep copies of all the paperwork. You’ll need to keep a record of the safety inspection for two years, and give a copy to all of your tenants within 28 days of the inspection. If your tenants change, they’ll need a copy of the Gas Safety Certificate before they move in. If your contract says the agent is responsible, then the Gas Safety (Installation and Use) Regulations 1998 are passed on to them.

Top tips

  • Legally you only have to carry out a gas safety inspection every twelve months, but it’s a good idea to get appliances checked between tenants too. Then you’ll be sure your appliances are in tip-top condition before your new tenants move in.
  • Installing a Carbon Monoxide (CO) alarm comes highly recommended – not just by us, but by HSE too. It’s the best way to make sure your tenants are safe from dangers of Carbon Monoxide poisoning. But an alarm should never replace regular maintenance and safety checks.

What you’ll get with a Gas Safety Certificate:

  • Your gas appliances will be checked for gas tightness.
  • If test points are available, standing and working pressure will be tested.
  • Your Gas Safe engineer will check burner pressure and gas rate against the manufacturers data plate.
  • Checks will be carried out for the provision of all necessary ventilation.
  • Flue flow will be tested to make sure products of combustion are removed.
  • All flame failure devices will be checked for satisfactory operation.
  • Where appropriate checks will be made for physical stability, presence and effectiveness of stability brackets.
  • Investigations for any evidence of unsafe operation will be made and reported.
  • Without completing all of the above checks an appliance can not be issued a Gas Safety Certificate.
