An upgrade ranges from new TRVs and smart thermostats through to full system replacement and radiator re-sizing for an extension. ### Who it's for Homeowners extending or refurbishing. Anyone with a 20+ year old system that's expensive to run and unreliable. Families with cold rooms that no amount of radiator-bleeding fixes. People moving from gravity-fed systems to mains-pressure unvented setups for stronger showers throughout the house. ### When it's needed Before the system fails entirely, and ideally before winter. A full install or major upgrade is a 2-5 day job — best planned in spring or summer, when boilers are widely in stock and engineer availability is at its best. Smart control upgrades can be retrofitted in a day at almost any time of year. ### Why a professional matters A central heating system is bigger than the sum of its parts. A new boiler on a poorly designed system underperforms badly; old radiators undersized for a well-insulated extension leave rooms cold; mechanical controls running a modern modulating boiler waste 15-20% of the appliance's potential efficiency. A proper system design integrates all of it. The Cost of Waiting ## An ageing or poorly designed system wastes more than it warms. What we routinely walk into on 25-year-old systems: - Sludge-clogged radiators with cold bottoms — the boiler running 80°C just to get rooms warm. - Microbore pipework crimped, restricted and corroded, hugely limiting flow to the furthest rooms. - Single-zone control on a 5-bedroom house, heating empty rooms 16 hours a day. - Old mechanical valves and timers stopping the boiler from modulating properly — 25% efficiency lost before any radiator is felt. The Consequence Most homes lose £300-£700 a year to badly configured central heating. A proper upgrade — new controls, balanced radiators, magnetic filtration, and where needed a system flush — usually pays for itself in 3-5 winters, before counting the boost in comfort.

No surprises. 01 ### Survey & Design We visit, measure rooms, calculate heat loss, assess existing pipework and discuss preferences (zoning, smart controls, radiator styles). 02 ### Fixed-Price Proposal Written quote including boiler/cylinder choice, radiator schedule, control specification, warranty and timeline. 03 ### Install Programme Typically 2-5 days. Floors protected, water and gas isolated correctly, pipework cleanly routed (and concealed where practical). 04 ### Flush & Commission Full power flush, fresh inhibitor, magnetic filter installed, every radiator balanced, controls programmed and tested. 05 ### Handover & Warranty Walk-through of all controls, manuals, warranty registration with the manufacturer, Gas Safe Building Notice filed. Why Choose On-Tap ## The benefits, plainly stated. ### Faster warm-up Properly sized radiators on a clean system warm rooms 30-50% faster than a tired old setup. ### Lower bills Combined boiler + controls + flush upgrades typically cut annual gas use by 25-35%. ### Full system warranty Up to 18-year manufacturer cover available on qualifying new installations. ### Comfort, room by room Smart zoning lets you heat the rooms you use, when you use them — and stop heating the rest. ### Future-proofed Magnetic filtration, modern inhibitor, correctly sized pipework — your system is set up for the next 15+ years. ### Sensible specification We won't over-engineer. The right kit for the property, not the most expensive option on the shelf. In Depth ## Central heating, designed properly — what that actually involves. There's far more to a good install than choosing a boiler. Here's what separates a well-designed system from a bodged one. ### Heat loss calculations and radiator sizing Every room loses heat at a calculable rate, depending on size, wall construction, glazing, exposure and ventilation. A correctly sized radiator delivers slightly more than that loss at design conditions (typically -3°C external, 21°C internal, 70/50°C flow/return). Under-sized radiators leave rooms cold; over-sized waste materials and money. Our quotes include a room-by-room calculation, not a glance at the existing radiators. ### Pipework, flow and balancing A system can have the right boiler and the right radiators, and still perform terribly if pipework is undersized or unbalanced. Microbore (8/10mm) installations in particular need careful balancing to ensure flow reaches the furthest radiators. Where pipework needs upgrading, we plan runs neatly — usually under floors, sometimes boxed — and always with proper isolation valves for future maintenance. ### Controls, zoning and smart heating A central heating system worth installing in 2026 deserves controls that match. We install Hive, Nest, tado°, Drayton Wiser and Vaillant vSMART, with full multi-zone control where the property and customer want it. For larger homes, splitting heating into 2-3 zones with independent schedules often saves more energy than any single boiler upgrade. ### Power flushing, filtration and water treatment Existing systems being upgraded should always be cleaned before a new boiler is fitted. A power flush combined with a chemical cleaner removes accumulated magnetite sludge, scale and debris. Once flushed, a magnetic filter (MagnaClean Pro 2 or Adey Pro 3) is fitted to catch new sludge, and fresh inhibitor (Sentinel X100 or similar) is dosed to manufacturer specification. Skipping any of these steps voids most boiler warranties — and shortens system life by years. FAQs ## Questions, answered. Anything else? Call [07815 022377](tel:+447815022377).
