Heating Equipment

The heating equipment heats the water for the system. There are many brands available and this is constantly expanding. We select the brands we use based on reliability, cost, supplier support and evidence of “independent testing”. With any mechanical system, breakdowns cause frustration to all those involved. We select equipment and design systems to minimize the likelihood of frustration. Our standard range of heating equipment is categorized by the energy source used. Within each category, there is usually a “standard” efficiency and the higher efficiency “upgrade” option. If required, we source heating equipment for special applications.
