New boilers for tall terraces, seafront houses and village homes

Boiler installation in Falmouth
Boiler installation in Falmouth runs from the homes off Dracaena Avenue to the period houses near Kimberley Park. If you're in one of the old merchants' houses on the streets climbing towards Pendennis Castle, you may well be in a conservation area, and Cornwall Council's character appraisals and surveys describe what gives each historic town its character. In practice that means no flue on a sash-windowed front, so a roof or rear route leaves the street side untouched. Tall houses with radiators on four floors often suit a system boiler with a cylinder in the old airing cupboard. For flats around Discovery Quay and Arwenack Street, we plan round shared walls and tight parking.
We take on combi boiler installation and boiler replacement in Penryn, Flushing, Mylor Bridge and Mawnan Smith.
Local homes, local know-how
Georgian and Victorian terraces and merchants' houses around the town centre and up towards Pendennis, larger Edwardian houses near Gyllyngvase and the seafront, and post-war estates on the edge of town. Mostly mains gas in town, with oil and LPG common in villages such as Constantine.
Not every home here is on mains gas. Our OFTEC registered technicians fit and service oil boilers and we install LPG boilers too.

The new boiler jobs we take on most
Basement boilers and condensate pumps
Many tall terraces near the harbour have a basement or lower-ground floor where the boiler fits best. If there's no drain lower than the boiler, the condensate can't flow away by gravity, so we fit a small condensate pump to lift it to a soil pipe or gully. It keeps the basement dry.
Edwardian houses near the beaches
Larger Edwardian homes near Gyllyngvase and Swanpool often have three or four bedrooms, two bathrooms and big rooms with high ceilings. A system boiler and unvented cylinder suits them, and we use coastal-grade flue kits on walls that face the sea.
Combi conversions in Penryn terraces
The granite and stone terraces in Penryn's old town often still have a tank-fed system with a cylinder taking up a bedroom cupboard. Converting to a combi frees that space and clears the loft, which matters in houses with small rooms and no room for storage.

Working around student terms and narrow harbour streets
Landlords with shared houses near the Penryn campus will find the summer holidays the best time to replace a boiler, when most tenants have left. Book the survey in spring so materials are ordered and the fit is done before the autumn term starts. We'll leave the commissioning paperwork you need for the property file.
The town centre has narrow streets and limited parking, and the roads close to the harbour get busy in summer. If your house is in the old core, tell us about loading spots or back lanes. In tall terraces, think about where the old boiler, the cylinder and the tanks will come out, as stairs can be steep and narrow.
If the house is in the conservation area and the flue has to move to the front, allow time for planning. Our page on combi conversion explains when losing the cylinder is a good idea and when it isn't.
Why choose Wisp for boiler installation in Falmouth
Student and shared lets
Letting near the Penryn campus? We fit robust boilers sized for a full shared house and hand over the commissioning paperwork landlords need.
Southerly gales
Houses along Cliff Road and above Gyllyngvase face straight into the weather. Flue position and terminal guards matter more here than inland.
Old back boilers
Some post-war terraces still have a back boiler behind the fire. Our back boiler replacement service removes it safely and makes good.
Spread the cost
Finance options are available on a new boiler, so you can pay monthly instead of in one go.

Boiler repair FalmouthBoiler Installation Falmouth FAQs
Our four-storey terrace near the harbour can't get the top floor warm. Is the boiler too small?
Sometimes, but more often it's the pipework: narrow old pipes, unbalanced radiators or sludge that has settled over decades. We test the system before recommending anything. A power flush and some radiator balancing is sometimes the cheaper fix, and a bigger boiler won't help if the water can't get upstairs.
Do you cover Flushing and Mylor?
Yes, both are a short drive round via Penryn. Flushing's old packet captains' houses need the same care with stone walls and flue routes as the terraces across the water. Out at Mylor Bridge you'll find more modern homes too, where a straightforward swap is often all that's needed.
Is it worth adding smart controls with a new boiler?
In a tall terrace, usually yes. Zoned heating lets you warm the floors you use, and smart radiator valves stop the top floor cooking while the basement stays chilly. We fit Hive, Nest, Tado and Drayton Wiser.
Our basement boiler has no drain nearby. How does the condensate get away?
We fit a condensate pump. It collects the slightly acidic water the boiler produces and pumps it up to a suitable drain, such as a soil stack or an outside gully. It's a small box under or beside the boiler, and it needs power from the same supply. We include it in the fixed quote.
When's the best time to replace the boiler in a student let?
During the summer holidays, when most students have moved out and the house is empty. That gives us clear access and avoids leaving tenants without heat or hot water. Book the survey in spring, as summer is busy for landlords and installers alike.
