Gas hydronic systems are the most popular choice for those with access to natural gas. Any hydronic system is capable of heating radiators, underfloor heating or a combination of the two. The Bosch range of condensing boilers provide both high efficiency and reliability.
If you have natural gas available, this system works out to be the best system based on overall related costs. LP gas is still the most expensive fuel but condensing boilers can reduce these running costs by up to 30%.
