Heating Installation & Design

Did you know that average house in the UK requires approximately 8-10Kw, yet the average boiler fitted is around 28Kw. This results in poor performance, a lack of efficiency and shorter running life of the appliance. Most of the high-efficiency condensing boilers that are installed do not actually condense properly. This due to the boiler running too hot for short periods causing the boiler to cycle. However, from the point of view of you the customer, if your radiators are hot and the water is up to temperature, then it is all working correctly, yes? No. System design, the correct pump selection and achieving the right temperature differential is vital. All the above should be considered if you are having a new boiler or a completely new system but unfortunately the industry does not teach any of this as standard. The knowledge required to get it right comes from working to best practices, and not just the standard practices required to tick a box. At Alton & Jones that is exactly what we do.

Air Source Heat Pumps 

The first thing that is needed before even thinking about the installation of a heat pump is a heat loss calculation. You need these figures to determine what size unit you need as it is essential to match the output of the unit to the heat requirements of the property. The report will also tell you what size radiators are needed for each room, and as the majority of radiator systems that are installed are oversized, this could mean that your radiators may be big enough. Once you have the heat loss calculation and radiator sizes, then it’s on to the system design. Pipe sizing is very important and there are things that can be fitted like buffers or heat exchangers that can help. With the correct size ASHP and a calculated system design, the unit can run at up to 500% efficiency which makes it cheaper than gas. The efficiency (or CoP) is all down to design and the type of ASHP installed.If you’re still after more information, click here where you will find lots of impartial consumer information.

Heat Loss

Your heat loss determines how much energy is required to keep a room at the determined temperature. The draughtier your house the greater the energy consumption. ​Once your heat loss calculation has been carried out, this will determine what size heat pump or gas boiler would be needed to heat your property. If the boiler that you have is greater in energy output than the maximum heat loss for your property, it will not work efficiently. Alton and Jones will always carry out a heat loss calculation as standard, and we also offer this as a separate service. To understand more about heat loss, click here
