Save up to £840 per year

According to the Energy Savings Trust new boilers with A-rated efficiencies of 90% or more means that they use less fuel, resulting in lower running costs and CO2 emissions. As heating and hot water account for around 55 per cent of what you spend in a year on energy bills, upgrading from G-rated with no controls, to A-rated high-efficiency condensing boiler and full set of heating controls will significantly cut your home’s CO2 emissions – AND could save you as much as £840 a year in a detached property, £480 semi-detached, £230 in a mid-floor flat, for example.

 Radiator Installation & Valve Replacement

Radiators can be the reason for lack of central heating, rather than the boiler. Especially if they are not regularly serviced. There are benefits to installing new radiators besides the wider, more modern range:

More energy efficient

Modern features and technology

Lower enery bills

Adding value to the property

Power Flushing your existing Heating System

Over time, sludge, rust and other corrosion build up up in your central heating system, clogging your radiators, pipes and boiler and causing noise, reduced efficiency and potentially boiler failure. By pumping cleansing agents around your entire central heating system, we can flush out ALL the corrosion and sludge – not just in the radiators and boiler, but in the pipework too, even in those impossible-to-reach places under the floorboards! – giving you lower heating bills, extending the life of your boiler and the rest of your system, and saving you money!

There are obvious and less obvious signs indicating a plumbing problem. For example if you are losing boiler pressure, you may start seeing or smelling mould in a room, you received a much higher water bill or located a damp patch on the floor or ceiling you may have a water leak. If you suspect a leak or any plumbing problem please call us for advice, to investigate and identify and fix the problem as soon as possible to avert more expensive damage.

What to do: If you suspect a leak in your property, locate the mains water stopcock under the kitchen sink or outside on the path and turn it clockwise to the off position. Then turn on all the tabs in the building to empty the pipes from excess water and call your plumber.

Upgrade your boiler

“Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, but they inevitably loose some heat in the hot gases that escape up the flue. A Condensing Boiler has a bigger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

Sometimes the flue gases get so cool that the water vapour in the gas condenses out (hence the name). When this happens, even more energy is recovered from the condensing vapour, and the efficiency gets higher still.” (Energy Savings Trust)
