Thanks Everyone for your ideas. We currently have Mitsubishi Air con/Heaters and althought they are more expensive to buy initially, they provide plenty of heat/air for the two bed house that we have and they are extremely economical and very quiet. However, we are thinking of moving to a bigger house in the future and wondered what other heating options were available. Our friends have a large detached house in Calis but they use oil heating which is EXTREMELY expensive.
