Often the bigger gain comes from the rest of the system, not the boiler itself. Dirty water, undersized radiators, poor circulation, and old controls are usually what make a house feel cold — not a failing boiler. We'll tell you honestly at the survey whether an upgrade, a boiler swap, or both will actually improve how your home feels.

Why People Choose Macara
A local heating company that gets the system right, not just the boiler.
Most cold-house problems aren't a boiler problem. They're a sludge problem, a radiator-sizing problem, or a controls problem. We survey properly and recommend the upgrade that actually changes how the house feels — not the biggest ticket we can write.
Gas Safe & LPG
Properly qualified for heating work
Every engineer on the van is Gas Safe registered and LPG certified. Central heating work often touches the boiler, gas pipework, or an unvented cylinder — it needs doing by someone legally allowed to do it.
- Gas Safe registered engineers (register no. 953527)
- LPG qualified for rural and off-grid systems
- Unvented hot water cylinder tickets held in-house
Local & Independent
Danderhall-based, covering all three Lothians
We live and work here. That means faster arrivals, engineers who know the local housing stock, and the same person quoting, installing, and supporting you after the work is done.
- Same engineer from survey through to handover
- 20+ years working on heating systems in the Lothians
- No sales scripts between you and the installer
Honest Scope
Upgrade only what actually needs upgrading
A lot of heating problems get quoted as 'you need a new boiler' when the real issue is sludge, radiator sizing, or controls. We survey properly before recommending work — and we'll tell you when the smaller fix is the right one.
- Free home survey before any quote is written
- Fixed written price once scope is agreed
- We'll say if a smaller upgrade will fix it
What We Cover
From single radiator changes to a full system refresh.
The same small team covers the whole system, so you're not juggling a plumber for the radiators, a gas engineer for the boiler, and an electrician for the controls. One call, one quote, one engineer who knows the job.
System Heart
New boilers & system replacements
Combi, system, and regular boiler installations sized properly for the house. Worcester Bosch, Vaillant, Ideal, Baxi, and Viessmann — we'll help you pick the right one.
Learn morePerformance Fix
Power flushing & system cleaning
Proper chemical and power flushing with system inhibitor, to clear sludge out of radiators and the heat exchanger. Protects the boiler and keeps manufacturer warranties valid.
Learn moreComfort Lift
Radiator changes & balancing
Right-sized radiators, low-profile replacements, heated towel rails, and proper system balancing — so every room actually heats up the way it should.
Learn moreEfficiency
Smart controls & wiring upgrades
OpenTherm-capable smart thermostats and weather compensation — the controls that let a modern boiler modulate properly, rather than simply switching on and off.
Learn moreRepair
Leaks, pump faults & noisy systems
Cold radiators, banging pipes, pressure loss, pump failures, seized valves — diagnosed properly before anything gets ripped out and replaced.
Learn moreRenewable Route
Heat pump-ready systems
If a heat pump is on the cards later, your radiators, pipework, and controls need to be right. We can upgrade a heating system now so it's ready for a low-flow-temperature heat source when you're ready.
Learn moreHow We Work
From first call to a warmer home in four clear steps.
No hard sell, no surprise prices, and no subcontracted installers showing up in branded vans. Here's what actually happens when you book a central heating job through Macara Heating.
01
Free home survey and honest diagnosis
We look at the boiler, the radiators, the pipework, the controls, and the water itself. Often the real problem isn't what the previous engineer said it was — and we tell you straight before any work is quoted.
No sales script. Just a proper look at the system.
02
Fixed written quote, clearly scoped
You get a fixed price covering the work, the parts, the flush where needed, the controls, and any pipework changes. No surprise extras once we start, and we'll break out optional work separately so you can decide what to include.
The number you see is the number you pay.
03
Tidy install by our own engineers
We protect floors and soft furnishings, work to the sequence we agreed at the quote, and keep you informed each day. Heating is normally back on at the end of each day unless we've warned you otherwise in advance.
Gas Safe registered engineers, never subcontracted.
04
Commissioning, handover & aftercare
We commission the system, balance the radiators, walk you through the new controls, and register any warranties on your behalf. If anything isn't right afterwards you're calling the same local engineer who did the job.
12-month workmanship warranty on every install.
Where We Work
Based in Danderhall. Covering Edinburgh and all three Lothians.
A genuinely local heating business, not an Edinburgh-only installer that treats Midlothian and East Lothian as an afterthought. We cover the whole region — and for larger system upgrades we'll happily travel further across Scotland's central belt.
Local coverage should mean faster response, better local knowledge, and less friction when your heating system needs proper attention.
Edinburgh, Midlothian, East Lothian, and West Lothian are covered as standard service area.
Faster response for breakdowns and no-heat calls, because we're local.
We'll travel further across Scotland's central belt for larger system upgrades, LPG conversions, and renewable-ready installs.
If you're near the edge of the Lothians or planning a larger central heating project, call us and we'll tell you straight away whether we can cover it.
