I am about to install a stratford tf90 boiler stove and intend to use this to run my central heating and domestic hot water. I have a four bedroomed house with 14 radiators and two bathrooms, which at present have electric showers but these may be replaced with mixer ones in the future. I would like to install a solar hot water system in a year or so so whatever i fit now should be able to cope with that. I don't know the best way forward ie thermal store v cylinder and would appreciate any advice.
