I have a wood burning boiler linked to a 3,000 litre storage tank. In summer it provides domestic hot water for up to five days. I was given to understand that with central heating on in winter it would last up to 3 days but I am lucky if sufficient heat lasts
for more than a day. Part of the property is an extension with underfloor heating which uses water at a much lower temperature and works well. The main house has a variety of radiators, some 40 years. Am a right in thinking these should be replaced with modern more efficient radiators which might conserve stored heat for longer ? And if so what type ?
