Skipped flushes, undersized pipework or wrong flue routing all void manufacturer warranties, we install so the warranty holds. The cost of getting it wrong ## What goes wrong with cheap heating installs A £100 saving on a boiler install can cost £2,000 in a voided warranty two years later. The economics only work if the install is done to manufacturer spec. If ignored - Voided boiler warranties Manufacturers require a magnetic filter, correct gas supply, system flush and commissioning notes. Skip any of those, the 10-year warranty is gone. - Undersized boiler, cold rooms Boiler capacity calculated on square metres alone (not heat-loss) leaves rear extensions and top-floor rooms permanently cold. - Sludge kills new boilers Installing a new boiler onto an old, unflushed system dumps sludge straight into the heat exchanger, expensive failure inside 2-3 years. - Wrong flue = CO risk Flue routing that doesn't meet manufacturer clearances is a life-safety issue, not just a compliance one. Common mistakes - Sizing on square metres, not heat loss Real heating design uses room-by-room heat-loss calculations. Anything less is a guess. - No system flush on boiler swap BS 7593 requires a power-flush and inhibitor on any boiler change. Skipping it is the #1 cause of premature failure. - No magnetic filter fitted Manufacturers require a magnetic system filter on install, it's now warranty-critical, not optional. How it works ## A step-by-step system, not a guess. 1. 01 Step 1 ### Free survey & heat-loss check We check current boiler, system age, gas supply size, flue routing and room-by-room heat loss. 2. 02 Step 2 ### Fixed written quote Itemised quote back inside the same week with recommended boiler, controls, filter and any pipework upgrades. 3. 03 Step 3 ### Install & pipework upgrades New boiler installed to manufacturer spec, magnetic filter fitted, gas supply upgraded if required, flue routed to clearance rules. 4. 04 Step 4 ### Power-flush & commissioning System power-flushed to BS 7593, inhibitor dosed, boiler commissioned with benchmark record signed off. 5. 05 Step 5 ### Sign-off & guarantee registration Gas Safe certificate issued, benchmark completed, manufacturer warranty registered on your behalf, 12-month workmanship guarantee. What you actually get ## Concrete outcomes, not adjectives. ### Warranty-safe installation Every boiler installed to full manufacturer spec so the 7-10 year warranty holds. ### Heat-loss designed Room-by-room heat-loss calc so every radiator is sized to actually warm the room. ### System power-flushed BS 7593-compliant flush and inhibitor on every boiler swap. ### Gas Safe registered All gas and boiler work carried out under Gas Safe registration with certificate issued. ### One accountable team Plumbing, gas, electrics and controls under one contract. ### 12-month guarantee Written workmanship guarantee on top of the manufacturer warranty.
