What we cover
How it works
Boilers, made simple
A boiler heats your home with warm water instead of forced air — quiet, even, draft-free heat that doesn't blow dust around.
- 01
Heat
The boiler warms water in a sealed loop, recovering heat from its own exhaust on high-efficiency models.
- 02
Circulate
A pump sends that hot water through pipes to radiators, baseboards, or tubing under your floors.
- 03
Radiate
Those warm surfaces gently heat each room — silent, even, and easy on allergies since nothing's being blown around.
Your options
Boilers options, explained
We size and install the right system for your home — not a catalogue. Here are the choices we fit most often, and who each one is for.
- Most popular
Combi Boiler
A compact wall unit that heats your home and makes hot water on demand — no separate tank needed.
Best for: smaller homes tight on space
- Heat + hot water
- Wall-mounted
- Premium
Condensing System Boiler
A floor-standing high-efficiency boiler that pairs with a tank for big heat and hot-water demand, recovering heat from its own exhaust.
Best for: larger homes, high demand
- High-efficiency
- High capacity
Radiant Floor Heating
Warm water runs through tubing under your floors, turning the whole floor into a gentle, silent, perfectly even radiator.
Best for: new builds and renovations
- Most even comfort
- Silent
What size do I need?
Sizing your boilers the right way
Boiler output is measured in BTUs per hour and set by a heat-loss calculation — your insulation, windows, and the type of radiators or floor loops you're feeding all factor in.
Measured in BTUs per hour
Sized to your home's heat loss, not its square footage alone
A rule of thumb gets you in the ballpark — but an oversized system short-cycles: it blasts on, shuts off, and wastes energy while heating or cooling unevenly. The right size comes from a proper load calculation, not a square-footage formula.
What we measure
- Square footage, layout, and ceiling height
- Insulation and how well the home is sealed
- Windows — size, number, and which way they face
- Our climate — cold winters and humid summers
We confirm the exact size during a free in-home assessment — so you get a system that fits your home, not a guess.

Common problems we solve
Boilers issues we fix
No heat from radiators
Circulator pump, air in the lines, or a control fault. Hydronic systems need a specialist's eye.
Boiler won't fire
Ignition, gas valve, or low water pressure. We diagnose the safety and ignition chain.
Leaks or pressure problems
A dropping pressure gauge or visible leak needs prompt attention before it spreads.
Uneven or noisy heat
Banging pipes or cold zones often trace to circulation or trapped air, not the boiler itself.
Repair or replace?
Signs it's time to act on your boilers
Repair or replace? A high-efficiency condensing boiler can cut gas use noticeably. If yours is old or failing, upgrading usually pays back in lower bills — and a combi unit can handle heat and hot water together.

What affects the cost
What affects the price
Every home is different, so we quote in writing after we see yours — no guesswork numbers online. Here's what actually moves the price.
Boiler type
Standard vs high-efficiency condensing vs combi (heat + hot water) changes cost and scope.
Output sizing
Matched to your home's heat loss and the number of zones or radiators.
System condition
Pumps, valves, expansion tank, and piping that may need replacing during the swap.
Venting & gas
High-efficiency boilers vent differently and may need gas-line adjustments.

Questions, answered
Boilers FAQs
Do you service all boiler types?
We service and replace residential and light-commercial gas boilers and hydronic/radiant systems.
Can a boiler be replaced with a combi unit?
Often, yes — a combi-boiler handles heating and hot water from one unit. We'll confirm it fits your setup.
Why is my boiler losing pressure?
Common causes are a leak, a failing expansion tank, or a faulty valve. We pin down which before topping it up.
Is boiler work licensed?
Yes — gas boiler work is done by TSSA-licensed technicians.
