Central heating installation and servicing in your area

Hepta installs, upgrades and services central heating in your area: new systems, extra radiators, pipework changes, pumps, valves and controls. We look at how your home loses and holds heat, then design a system that heats it evenly. Call 07477 877199 or send us the details to start.

What it covers

Central heating works best when it is designed for the house it serves. Radiators sized to the rooms, pipework sized to the radiators, a boiler matched to both and controls that let you heat only what you need. When any of those is off, you notice it in cold rooms and high bills.

We install complete systems, add to existing ones and service what is already there. If your heating works but never feels right, we start with a look at balance, circulation and controls before suggesting anything bigger.

Questions about central heating installation & servicing

Typically the system is unbalanced, the radiators are undersized, or sludge restricts flow to part of the circuit. We check balance, pump speed and radiator size and fix the cause.

A yearly check is the usual recommendation. It keeps the system efficient, catches small problems early and helps avoid breakdowns in winter. We can service the system and tell you what we find.

Usually yes. We check that the boiler and pipework can support the extra radiator, choose the right size for the room and connect it neatly. If the system is at its limit, we will explain what would help.

It can be, particularly for new builds and extensions. It works at lower temperatures and suits some boilers better than others. We cover this in detail on our underfloor heating page.

A programmer and room thermostat are the basics. Thermostatic radiator valves add room by room control, and smart thermostats add remote control. We recommend what fits your home and how you live in it.

We are based in Epsom and cover Epsom, Ewell, Ashtead, Leatherhead, Banstead, Cheam, Sutton and Worcester Park, along with Stoneleigh, Esher, Chessington, Cobham, Surbiton, Kingston upon Thames, New Malden, Carshalton, Wallington, Purley, Coulsdon, Reigate, Redhill, Croydon, Morden and Wimbledon. Each of those has its own page for central heating installation and servicing, and you can also send us your town through the contact form.

Bleed the radiators that feel cold at the top, check the room thermostat and timer settings, and note which rooms are cold. If the system still does not heat evenly, contact us.

Which rooms are too cold or too hot, the age of the system and boiler, any recent building work, and whether you want to add rooms or change controls.

Uneven heating usually comes from poor balancing, sludge in the system, a weak pump, or radiators that are too small for the rooms. Extensions often make it worse.

Yes. Use the contact form with your name, phone number, town and a short description of the job. Pick a preferred contact time if you like; it is a preference only. For anything urgent, call 07477 877199.
