In a low heat loss home, a lot of times Domestic hot water demand can outstrip heat demand, the buffer tank can help a lower output boiler keep up with demand. If there is a huge mismatch it may be better to separate out the uses. This allows the system to be more flexible, and possibly increasing system efficiency. Also Solar Thermal? Unless you are hard up on solar access it's just not worth it. It may be cheap enough if you build you own flat plate collectors, but factor in your time, and the decreased system reliability and I doubt the cost/benefit is there. |
