With the current Gas market might not be a great idea. The most efficient way of heating here is 'heat pumps', basically air conditioning that both heats & cools, heat mode you get 3 times the output for the same cost. (Modern inverter units are very cost efficient & take little power) For example, the cost to produce 1000 watts cool will give you 3000 watts of heat. For just water heating Butane gas bottles are still pretty efficient & still popular in Spain, at the moment about 15 Euro capped by the government. However, you will need a huge outside Butane tank to run a central heating system. (Unless you have an underground direct natural gas supply, then you know from the news the price will rocket) Heat pumps are also used to heat pools, many experts here on their use, from single units to large ones that feed either multiple units or house ducking vents. .
