A simple guide to your new central heating installation
Let us guide a bit through your heating and hot water systems including vented and unvented systems, choosing a boiler, choosing the right size boiler and provide you with a table comparing different fuel costs.
Think of a central heating installation in two parts: the bit that generates the heat, and the bit that distributes that heat around your home. the heat around the house is required in two forms — for space heating (i.e. keeping you warm) and for hot water (i.e. for showers etc). So, the simplest of all systems would have:
- a boiler (which uses power to heat up water and incorporates a pump to move it around);
- piping (to move that warm water around your house);
- emitters (whether it be radiators or underfloor heating);
- hot water cylinder (to store hot water for use as required, although these are not required with a ‘combi’ boiler — more on which later).
Choosing the Boiler (central heating installation)
The boiler is the most important part of the central heating installation and your choice will impact on how the system operates and its efficiency. Your new boiler will by definition be at least 90% efficient (i.e. convert 90% of the energy it uses into heat) and it has to be a condensing boiler (which utilizes the heat from the exhaust gasses within the boiler for added efficiency). Most people will opt for a regular ‘system’ boiler but you could also opt for a ‘combi’.
As the name suggests, a combi boiler combines a central heating boiler with a water heater. Hot water is produced directly from the boiler and is given priority over the heating requirements. This is a sealed system and because it heats water instantaneously, there is no need for hot water storage. The main issue tends to be that smaller models struggle to produce the amount of hot water on demand that a larger family needs. Be aware that solar panels won’t work in tandem with a combi boiler system.
What size boiler do I need for my central heating installation?
Boilers come in different sizes (measured in kW) and you need to specify the right one — a boiler that’s too large will not only be more expensive but will operate less efficiently than an adequately sized model. Bear in mind that plumbers will be more likely to oversize as they don’t want callbacks from problems relating to a small model, and the capital cost is passed on to you anyway. Many of the boiler suppliers offer online guides for choosing the right size. You can have a stab yourself by adding up the required heat output from the radiators or underfloor heating system (taking into account room sizes, insulation levels and window sizes; this can usually be calculated on radiator company websites) then adding 3kW for hot water and a 10% buffer. Typical boiler requirements for a larger detached Typical boiler requirements for a larger detached house would be in the region of 30kW.
The Different Systems — The Vented System
In this type of system, the hot water is heated and stored in a cylinder in the airing cupboard, with the storage tank in the loft supplying cold water directly to the cylinder’s base. The hot water rises to the top of the cylinder (replaced by cold from the storage tank) and is drawn off via a vent pipe to the hot taps. (Because water expands when heated, it needs somewhere to expand to — the vent pipe can accommodate some of this; an expansion tank in the loft takes the excess).
Vented systems can either be direct or indirect — the difference being that indirect systems accommodate a heat exchanger in the cylinder to heat up water in the cylinder itself, while direct systems heat up the water in the boiler for storage in the cylinder (although most direct systems accommodate an electric immersion heater which allows heating of water in the cylinder independently of the boiler).
