Commercial Heating Services

Sized for your building, not your old boiler. Swapping a commercial boiler like for like copies any mistakes in the original design. Insulation, glazing, extensions and the way rooms are used all change over the years, so we size new heating from a heat-loss calculation, which works out how much heat each area loses on a cold day. Hot water is sized separately, around the busiest moment of the day: morning showers in a care home, or the breakfast rush in a hotel. Getting both right often means smaller plant that runs more efficiently.

Plant rooms, back-up and controls. A good plant room leaves space to service every boiler and pump without taking the system apart. In most commercial buildings a cascade makes sense: two or more smaller boilers working together instead of one large one. If one fails or is being serviced, the others keep the building warm, and on milder days only one needs to run. The controls then decide when and how hard the plant works, with separate time and temperature zones and weather compensation, which turns the water temperature down as it gets milder outside.

What affects the cost of commercial heating. Every building is different, so we price each job from the survey. The things that move the price most are the type of system (gas boilers, a heat pump or a hybrid of the two), the size of the building and how much heat it needs, how easy the plant room is to reach for deliveries and lifting, how much pipework and how many radiators need replacing, and whether the work has to be phased so the building can stay open. Running costs then depend on fuel prices, how well the system is controlled and how regularly it's serviced.

Different buildings, different problems. Care homes need steady warmth around the clock, radiators that stay safe to touch and hot water that's protected against scalding and legionella. Apartment blocks often share one plant room, so heat has to be shared fairly and metered. Schools sit empty at weekends and in the holidays, so the controls should stop heating empty classrooms. Hotels have sharp peaks in hot water use. Offices need zones that match how each floor is used. Older and listed buildings need pipe routes and flues that respect the building, with consent where it's needed.

What our customers say.

"We hired agg Kent to upgrade our large family home with high pressure hot water and new plant room. We are now able to enjoy our house to its full potential and will be looking to have them back to fit air conditioning throughout. Thank you Josh and Charlie for all your hard work and being very accommodating to our requirements" - Georgie, Google
