Questions homeowners ask before upgrading radiators, controls, pipework, or the wider heating system in an Edinburgh or Lothians home.
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.
Power flushing clears sludge, rust, and debris from your central heating system. If your radiators are cold at the bottom, your boiler is noisy, or the house takes ages to warm up, a flush is often the fix. We only recommend it where the condition of the system actually justifies it.
Usually yes, if your existing system is more than a few years old and hasn't been flushed before. Black sludge, cold radiators, and noisy pipes are all signs the water needs cleaning properly. A power flush protects the new boiler and keeps the manufacturer warranty valid.
Cold at the bottom is almost always sludge in the radiator. Cold at the top is usually trapped air. Radiators that stay cold entirely can be a circulation issue, a stuck valve, or an unbalanced system. All of it is fixable without ripping the heating out.
For most homes, yes — a properly fitted smart thermostat pays for itself in comfort and wasted heating. The bigger gain is usually the weather compensation and accurate room sensing, not the phone app. We fit controls that actually talk to the boiler properly, not ones that just switch it on and off.
Most upgrades are less disruptive than people expect. A power flush and radiator changes are typically a day. A controls upgrade is usually a half-day. A full system refresh with new pipework runs two to four days depending on the house — we work to a clear schedule and tidy up properly each evening.
Yes. New boilers carry the manufacturer's warranty (up to 10 years on some models, provided the system is properly cleaned and annually serviced). New radiators and valves carry their own manufacturer warranties, and the workmanship on our installs is covered for 12 months as standard.
