Our house has a radiator heating system, fired by a large Marshall wood burner.
- some level of heat storage – so that we don’t have to run the wood fire whenever we want heat
- a way for that storage to stay reasonably warm for 4-5 days, so we can go away and have the heating automatically run before we return home
- thermostat control on the individual radiators so we can hold a temperature, rather than adjusting temperature through how vigorously we stoke the fire
- zoning of the rooms, so that those rooms not in use can not consume heat
- allow me to run the boiler hard, rather than damping it down, which reduces pollution and increases heat output from a given weight of wood
- the boiler also runs the domestic hot water (DHW) in winter, currently that’s an open cylinder rather than mains pressure, it’s a bit small, and takes forever to get hot water to the kitchen
- the thermostat on the boiler that controls the pump is slow to cycle, leading to the boiler overheating and boiling the water, rather than heating it. This is wasteful of heat.
