At the moment this is fairly idle musing, but we're looking at moving and many of the houses in our area are period, so there's a good chance we would look at moving into one.
My understanding is that alternatives to gas and oil boilers really need to be fitted in well-insulated properties because the water temperatures they generate are so much lower. But how is this going to work in period houses which are often poorly-insulated and often impossible to get up to a really good level? Is biomass the only alternative? And if you keep your boiler going past 2035 will oil just become increasingly difficult and expensive to get hold of as time goes on?
Really interested in thoughts/experiences of people currently living in these sorts of properties.
