Plain-English breakdown, so you know exactly what you're paying for, and why it matters before we set foot on site. ### What it is We install, repair and service domestic gas boilers, combi, system and regular, across St Albans, Hertfordshire and surrounding towns. Every install includes a flush, a magnetic system filter, fresh isolation valves and proper commissioning paperwork. ### Who it's for Homeowners replacing a 10–15 year old boiler, landlords needing a CP12 plus a reliable swap, and growing families moving from a combi to a system boiler with a hot water cylinder. ### When you need it When your hot water is inconsistent, you're losing pressure weekly, the unit is over a decade old, your gas bills are climbing without explanation, or your existing boiler keeps locking out with fault codes. ### Why it matters Boilers are the single most expensive bit of kit in your home. A badly sized or rushed install kills efficiency, voids warranties and leads to recurring breakdowns. A Gas Safe engineer who takes the time to size the unit to your radiators, flow rate and demand is the difference between 15 years of quiet running and a £600 callout every winter. The cost of doing nothing ## What goes wrong when this is ignored. Putting off a boiler issue almost always costs more than fixing it. Heating systems fail in cascades, one weak component overloads the next. ### Risks of waiting - A boiler running on dirty water will burn its heat exchanger within 2–3 winters, a £1,400+ part on most modern combis. - Low pressure left unchecked leads to pump dry-running and seal failure, which floods the airing cupboard floor. - An unserviced gas boiler can shift out of safe combustion tolerance, carbon monoxide is invisible and odourless. - Letting a manufacturer warranty lapse (no annual service) can leave you facing a full replacement cost in year 4 or 5. ### Common mistakes - Choosing a boiler by price alone, undersized units short-cycle and die early, oversized units waste gas. - Letting a non-Gas-Safe handyman touch the gas, illegal, uninsurable and dangerous. - Skipping a system flush on a new install, voids most manufacturer warranties immediately. - Accepting verbal quotes, every Heatrite job is quoted in writing with parts, labour and warranty terms itemised. Our process ## How the job actually runs. Same system every time. No improvising on your floor. 1. 01 ### Free home survey We measure your radiators, check your gas supply, flow rate and flue route, and ask how you actually use hot water. No guesswork, no over-spec. 2. 02 ### Fixed written quote You get a printed quote within 24 hours showing make, model, warranty, parts, labour and timeline. No 'estimated extras'. 3. 03 ### Install in 1 day (combi swap) Most combi swaps are floor-to-finish in a single day. System and regular boilers typically run 1.5–2 days including cylinder work. 4. 04 ### Power flush & commissioning Every install includes a chemical flush, magnetic filter, fresh inhibitor, full pressure test and a commissioning certificate. 5. 05 ### Registration & guarantee We register your warranty with the manufacturer, lodge the gas notification with Gas Safe and hand you the paperwork before we leave. What you get ## The outcomes that matter. ### Lower gas bills from day one A correctly sized A-rated condensing boiler typically cuts gas usage 15–30% versus a 12+ year old unit. ### 10-year manufacturer warranty On Worcester Bosch and Vaillant flagship models, backed by Heatrite's own workmanship guarantee on the pipework. ### Quiet, consistent hot water Properly flushed systems run silent, no kettling, no banging radiators at 6am. ### Safe by design Every Heatrite install includes a CO alarm fit, gas tightness test and combustion analysis. Documented. ### Same-week installation Most jobs booked Monday are fitted by Friday. Emergency replacements often same-day in our core patch. ### One engineer, start to finish Same face on day one and day five. Direct mobile number for any post-install question. In depth ## Everything worth knowing before you book. The details a salesperson skips. Skim it, or read every word, both are useful. Questions on this? Talk to a Gas Safe engineer direct.

Combi boilers heat water on demand and suit 1–2 bathroom homes with one shower running at a time; they free up airing cupboard space and are the most common St Albans swap. System boilers feed a sealed hot water cylinder and are the right pick for 3+ bedroom homes, multiple bathrooms, or anywhere two showers may run at once. Regular (heat-only) boilers use a feed-and-expansion tank in the loft and a hot water cylinder, usually retained in older properties where pipework changes would be intrusive. We'll spec the right type after measuring your incoming mains flow rate at the kitchen tap, not by guessing from room count. ### Brands we fit and why We install Worcester Bosch (Greenstar 4000, 8000 Life and Style), Vaillant (ecoTEC Plus and ecoFit Pure), and Ideal Logic Max. Each is chosen for parts availability across Hertfordshire and the Home Counties, engineer-friendly internals, and genuine 10-year warranty performance. We don't fit budget brands that look cheap on paper but cost £400 in a callout when a sensor fails in year 3. ### Boiler repair, what we typically fix Recurring fault codes (F22, F75, EA, E168), low pressure that returns within days, kettling and banging, hot water that runs cold mid-shower, frozen condensate pipes in winter, diverter valve failures, PCB resets, fan and pump replacements, expansion vessel re-pressurisation. If a repair quote approaches 40% of replacement cost on a unit over 8 years old, we'll tell you straight, not push the repair. ### Annual boiler servicing A proper annual service is not a 15-minute visual check. We strip the burner, vacuum the combustion chamber, test gas pressure at the inlet, run a flue gas analyser, check the expansion vessel charge, and re-dose inhibitor if your magnetic filter is loaded. You get a written service report, which most manufacturers now require to keep the warranty live. ### Landlord gas safety (CP12) We issue Landlord Gas Safety Records (CP12) for every gas appliance in a let property, with photos and engineer's notes uploaded to a secure portal. Booked in 48 hours, completed in under an hour per property, and stored for 7 years on our system in case of dispute. General work gallery ## Recent Heatrite jobs that show the standard of our work.
