Heat pump installation Clyst St Mary: a 1310 bridge at one end, a 1960s estate at the other
Clyst St Mary’s bridge over the Clyst was rebuilt in 1310, the oldest in Devon. Heat pump installation Clyst St Mary gets the same care from James, who measures every room himself before choosing any equipment.
James and the team provided a first rate end to end service, our old oil boiler failed on Good Friday and within 3/4 weeks we were up and running with a new energy efficient air source heating system.

What we measure, fit and hand over on a Clyst St Mary install
Design is the part that decides whether a heat pump behaves itself. It is also the part that gets skipped. Everything below is inside the price we quote you, and none of it is an optional extra.
- A full room-by-room heat loss survey. Wall build-up, glazing, orientation and exposure, recorded on site, never inferred from a floor area or a postcode.
- Unit sizing taken from those figures. The system is specified to cover your coldest day without carrying capacity you pay for and never use.
- A written radiator schedule. Which of yours stay and which need upsizing to run well at a lower flow temperature. In most properties, most of them stay.
- The heat pump, cylinder, pipework and controls. A heat-pump-specific hot water cylinder, plus all the pipework, wiring and controls that run it, supplied and fitted as one job.
- Weather-compensating controls where they earn their place. The system tracks the outside temperature and modulates rather than cycling hard on and off.
- Commissioning and optimisation on site. The system leaves working the way the design said it would, not however the factory happened to ship it.
- A proper handover. How to drive the system covered in plain terms, and servicing arranged for when it falls due.
We design and fit underfloor heating as well. If you already have it, a low-temperature system suits it far better than an oil boiler ever did.
Heat pump installation Clyst St Mary: seven centuries of building in one village
Walk from the river up to the A3052 and you pass through most of English building history inside about a mile.
- The bridge over the Clyst was rebuilt in 1310 and is the oldest in Devon; the cottages nearest it are solid-walled and heavy, holding and losing heat slowly.
- The old Winslade manor grounds went up as 1960s housing, and a mile north at Sowton it turns to farms standing alone in open ground with nothing to shelter them. Exeter is three miles west, and we cover heat pump installations in Exeter.
None of those buildings behave the same way in a cold week, and no floor-area calculator can tell them apart.
- Our room-by-room heat loss survey records wall construction, glazing, orientation and exposure in every room, and the unit size, radiator schedule and flow temperatures fall out of those figures rather than a rule of thumb.
- James Stalker moved into heat pumps in 2010 and has upwards of 100 systems behind him, all built the same way: see how we design an air source heat pump installation.
Mains gas reaches parts of the village and thins out across the farmland around it, and the edge varies plot by plot, so we check yours.
- Off the grid on oil or LPG, the case is at its strongest: a fuel you buy ahead, store in the garden and ration through February, traded for one that arrives down a wire.
- Replacing an oil boiler with a heat pump is what puts a property in reach of the higher grant rate.

Stephen M. · Google review · five stars
He audits other installers for a living.
- NAPIT send James out as a freelance MCS assessor to judge other firms’ heat pump work against the standard.
- Yours gets designed to survive the audit he would run on it himself.
Room-by-room measurement, not a postcode estimate.
- Every wall build-up, window and radiator recorded.
- Fit too much capacity and the unit switches itself on and off all day for nothing; fit too little and the house finds you out in a cold February.
Older and period properties welcome.
- Solid walls, cob and stone, including the cottages down by the bridge.
- “Not suitable” is nearly always a company declining the design work, not a verdict on the house.
The grant deducted before you pay, about a week on site.
- We are MCS certified, so we file the Boiler Upgrade Scheme application and knock it straight off the quoted figure.
- We keep to one or two jobs at once, and Exmouth is a short run back down the A376 when you need us afterwards. Clyst St Mary sits squarely inside the areas we cover.
What homeowners say on Google
Heat pump installation Clyst St Mary: grants, VAT and honest running costs
The Boiler Upgrade Scheme in Clyst St Mary is installer-led: we file the application and deduct it from the figure we quote you, so no money of yours ever goes out and comes back.
Check if your home qualifiesWe are not going to dress up the running costs.
Put a heat pump against oil on an ordinary tariff and the yearly difference is usually smaller than the advertising suggests, and anyone naming you a number before measuring the house is guessing.
- What changes is the shape of the bill: for oil-heated properties out towards Sowton and Clyst St George, the deliveries stop and the tank stops mattering, and a heat-pump-specific electricity tariff improves the arithmetic further.
Grant figures correct as of August 2026. Eligibility criteria apply and are confirmed at your free home assessment.
-
Properties on mains gas can qualify for £7,500.
- Whether your Clyst St Mary home qualifies comes down to the property and your circumstances, settled at the free assessment before anything is priced or promised. Both figures are for owner-occupiers in England and Wales.
- Where a property sits off the mains gas grid and burns oil or LPG, the Boiler Upgrade Scheme puts £9,000 towards an air-to-water heat pump, on applications submitted up to 31 March 2027. That date is the cut-off on the higher figure only, not on the scheme itself: see how the off-grid uplift actually works.
- VAT on the installation sits at 0% until 31 March 2027.
How we choose the heat pump and the pre-plumbed cylinder
For the typical off-grid home the measured heat loss gives the size of unit, and the room figures show which radiators can stay as they are.
We choose the cylinder for your home, as we do the heat pump, and it usually arrives pre-plumbed with its valves and stats fitted.
We fit weather-compensating controls where they add value, and set them up at commissioning.
We are not tied to one manufacturer: James picks the heat pump that suits each property, and we often fit Ideal, whose 4 to 10 kW range matches the heat loss figures on most properties around here, from the solid-walled cottages by the bridge to the estate houses off Winslade Park.
Ideal’s units are built in the UK, so replacement parts turn up quickly.
The cylinder we usually fit arrives pre-plumbed, with the filter, diverter valve, cylinder stat and overheat stat already fitted, which means fewer joints made on your landing and fewer places for the system to fail in year three, a large part of why about a week on site is a promise we can keep. We do not force a house to fit a product. Where your Clyst St Mary survey figures land outside that range, we design around them and tell you so.

Exmouth
A 1930s six-bedroom home with 34 windows
The owners doubted a heat pump could heat an older, larger property. A detailed design running at a low 47 degrees, with seven radiators upgraded and the rest kept, proved it could, comfortably.
West Hill · Ottery St Mary
The job three installers said could not be done
The owners wanted their hot water cylinder relocated to the garage. Three previous companies refused. We redesigned the pipework and did it, on a 311m² home with uninsulated floors.
Newton Abbot
A period home others had written off
We redesigned and re-piped the entire heating system for low-temperature running, and added radiators to rooms that never had them. “Too old” is usually a design problem, not a dead end.
We install across East Devon, including Clyst St Mary, Exmouth, Budleigh Salterton, Sidmouth, Ottery St Mary, Woodbury, Lympstone, Newton Poppleford, West Hill and Honiton. Up the M5, heat pump installation in Cullompton is part of the same patch. A couple of miles south down the lanes sits Woodbury Salterton, cottages and cob below the common. East along the A3052, air source heat pumps in Aylesbeare go into the village, the hamlets and the old farm buildings between them.
Street, Somerset: three installers, three different answers. We designed it correctly.
Before calling us, this homeowner had already had two national installers and another company out, and been handed completely conflicting advice, one proposing an oversized 16kW system, another saying the property was not suitable for a heat pump at all. Our room-by-room heat loss survey showed the home was suitable, but nowhere near the 16kW that had been quoted. We sized it correctly, upgraded only the radiators that genuinely needed it, and fitted an Ideal Logic Air matched to the actual heat loss rather than the quote sheet.
Heat pump installation Clyst St Mary: common questions
Nobody can tell you that from a postcode. James leaves a fixed estimate at your Clyst St Mary property during the free home assessment, and the heat loss survey converts it into a firm quote inside 24 hours, with the grant already taken off.
Book my free home assessmentOff the mains gas grid and running on oil or LPG, a Clyst St Mary property can qualify for £9,000, on applications submitted up to 31 March 2027. On mains gas it can qualify for £7,500 instead. Neither figure is automatic, so we establish which one applies to you at the free home assessment.
Book my free home assessmentUsually yes, once somebody does the arithmetic. A solid stone or cob wall behaves nothing like a modern cavity, which makes room-by-room measurement more important in older Clyst St Mary cottages, not less. “It cannot be done” is nearly always shorthand for “we would rather not design it”.
Book my free home assessmentYes. A newer Clyst St Mary house is quicker to measure, because the fabric tends to behave closer to the drawings, but we measure it rather than assume it. Sizing off floor area is how properties end up with oversized units that short-cycle, and that happens on 1960s estates just as readily as in old cottages.
Book my free home assessmentPosition is settled at the free home assessment, not on installation day. James walks the plot at your Clyst St Mary property, picks a spot that suits the condensate run and the drainage, and the MCS sound calculation is worked out for wherever that turns out to be.
Book my free home assessmentAbout a week. A Monday start is normal and the commissioning is done by the end of that same week. We hold to one or two jobs at a time, so a Clyst St Mary install is never queued behind six others.
