TRVs are Thermostatic Radiator Valves and these can be fitted in place of your existing radiator valves. Part L Building Regulations published by the Government recommend the use of TRVs as they are an energy saving product. They allow you to set individual heating levels in each of the rooms they are fitted. When the heating system is turned on, the radiator will heat up to the pre-determined level you have set. The valve will then automatically turn itself on and off to maintain the desired room temperature, until the heating is switched off. TRVs can help to save energy and consequently reduce your gas bill as they stop your heating system wasting unnecessary heat.
A Fused Spur is an electric point with its own removable fuse and an isolation switch. Current regulations require your new boiler to have an electricity supply from a fused spur, as this ensures that when an engineer carry’s out routine maintenance on your boiler, there is no danger of electrocution. The engineer is able to turn off the switch and remove the fuse, and carry out the service without the danger of someone accidentally switching on the appliance.
If your existing boiler does not have a fused spur, then we will need to fit a new one close to the new boiler position. This will be carried out by a fully qualified and approved electrician, which if it’s required we have arranged and included in this quotation.
A Powerflush is recommended prior to the installation of a new boiler. Over time your heating system builds up sludge and other sediment, which can drastically reduce the efficiency and performance of the boiler. A Powerflush thoroughly cleans your heating system, ensuring that your new boiler works as effectively as possible. Our engineers will add a chemical cleaner to your system, and then connect a portable pump, which produces a high pressure flow of water. Each of your radiators will then be turned on and off, and the pressure is directed all over the system, ensuring that your system is cleaned as thoroughly as possible. A Powerflush will ensure your new boiler works as efficiently as possible, helping to reduce your gas bills. Many of the boiler manufacturers who we use also recommend Powerflushing, and it has been proven to increase the life expectancy of new boilers.
ME Bonding is the electrical earth wiring in your property. This is an essential safety requirement in every home. It ensures that all metal parts of your new boiler, copper pipework and your existing bath and / or shower are all ‘earthed’ to the ground. This prevents any of the metal parts of your new heating system becoming electrically charged and prevents electric shocks.
It is very common to find homes where the earthing requires upgrading, but our Sales Consultants are aware of what to look for, and if they feel your earthing is not up to standard, they will recommend that one of our team of electricans inspect your property and advise you of any work which is required. In most cases the work will need to be carried out by your electricity supplier and is free of charge on health and safety grounds
In most cases, your new heating system will require at least a few new controls. These include: programmers, room thermostats, hot water cylinder thermostats, 2-port and 3-port valves. Motorised valves divert heat between your radiators and your hot water allowing individual control of both, for example, in the Summer you are unlikely to want your radiators on, but will still require your boiler to heat your hot water.
The specification which your home requires depends very much on the size and design of your property, together with the expectations you have regarding the characteristics of your new heating system. The controls which our Sales Consultant has chosen for you, are specifically designed to give you total control of your system.
All full installations (new boiler and radiators) we carry out are ‘hot flushed’ upon completion of the work. This ensures that your new system is as clean as possible, which means it will run as efficiently as possible. Firstly, debris which may have got in to the pipes during the installation is removed by filling the boiler with cold water and adding a cleaning agent, this is then rinsed through the entire system. Secondly, the system is filled again and this time the new boiler is fired and the system is rinsed at high temperature, this ensures that any stray solder or ‘flux’ (the material used to connect pipes) is removed. Finally the system is filled for the last time, and an ‘inhibitor’ is added to it, this is a chemical which helps to reduce corrosion in the system. This procedure will also be carried out for boiler changes, where we do not Powerflush the system.
If your system is gravity fed, we will need to convert it to a ‘Fully Pumped’ system. This is a requirement of new high efficiency boilers. The advantage of this is that your new system will run far more efficiently, and this means your boiler will be on for a shorter period, thus reducing your gas consumption.
