Hi all! Was wondering if anyone can help me. In the middle of a self-build and we were originally planning on installing geothermal heat pump but doesn't look like this is going to work out now due to a number of factors. We are looking into gas heating as an alternative and was just wondering if anyone can advise me on approximate cost of filling an LPG bulk tank and how long a fill would last. House is approx 2400 sq feet and will be using lpg for underfloor heating and hot water only. Thanks!
