Most comparisons are written by people selling one or the other. We install both underfloor heating and MCS certified heat pumps across Cheshire, and we turn work down when a property is not suited. Here is what genuinely separates the two technologies, and what decides which one is right for your home. ## The one number that decides everything: flow temperature A gas boiler burns fuel and can push water round your radiators at 60, 70 or 80 degrees without caring much about efficiency. A heat pump does something completely different. It moves heat from the outside air into your home, and the harder you make it work, the less efficient it becomes. Efficiency is measured as a coefficient of performance. At a flow temperature of 35 degrees, a good air source heat pump delivers roughly 4 units of heat for every unit of electricity. Push the same unit to 55 degrees and that can drop to around 2.5. Since electricity costs more per unit than gas, the entire running cost argument comes down to whether your home can be heated at a low flow temperature. This is the reason we talk about emitters before we talk about heat pumps. Get the emitters right and a heat pump comfortably beats a boiler on running cost. Get them wrong and it will not. ## Running costs compared ### Coming off mains gas This is the closest contest. A modern condensing gas boiler is around 90 percent efficient, and gas is significantly cheaper per unit than electricity. A heat pump running at 35 degrees through underfloor heating typically lands slightly below the cost of running that boiler. A heat pump running at 50 degrees through unchanged radiators typically lands slightly above it. The design work is the difference between those two outcomes. ### Coming off oil or LPG Here the heat pump wins clearly and immediately. Oil and LPG are expensive, price volatile and involve deliveries and tanks. Cheshire properties off the gas grid are the strongest candidates we see, and they usually recover the cost difference far faster than a gas replacement would. ### Coming off electric storage heating A heat pump replacing direct electric heating is close to a guaranteed win, because you are replacing a system that delivers one unit of heat per unit of electricity with one that delivers three or four. Layer on the £7,500 Boiler Upgrade Scheme grant and the capital gap narrows sharply. Our [Boiler Upgrade Scheme guide](/guides/boiler-upgrade-scheme-grant) sets out exactly how that works and who qualifies. ## Radiators vs underfloor heating A radiator heats a small surface area to a high temperature. Underfloor heating heats an enormous surface area, your whole floor, to a low temperature. For a heat pump, the second approach is transformative. It is the difference between the system working at the top of its efficiency curve and struggling at the bottom of it. The objection is always the same: we do not want the floors lifted. In an occupied home that is a fair objection, and it is exactly why [retrofit floor milling](/services/retrofit-floor-milling) exists. We cut precise channels into the existing concrete or screed with dust extracted equipment, lay the pipe into those channels and reinstate. The floor level barely moves, doors and skirtings stay as they are, and there is no rebuild. Where milling is not viable, low profile overlay panels add around 15mm to the floor build up and achieve much of the same benefit. Both routes are covered under [retrofit domestic installations](/services/retrofit-domestic), and you can see the finished work in our [case studies](/case-studies). If you keep radiators, expect the heat loss calculation to flag a handful of rooms needing a larger emitter. It is very rarely every room, and it is very rarely as disruptive as people fear. ## Comfort, space, noise and lifespan - **Comfort.** A boiler heats in bursts, so rooms swing warm then cool. A heat pump runs steadily at a lower temperature, which most people describe as more even. With underfloor heating there are no cold corners and no hot radiator faces. - **Space.** A heat pump needs an outdoor unit with clear airflow and, in nearly all cases, a hot water cylinder indoors. If you have a combi boiler and no airing cupboard, finding cylinder space is the real design challenge, not the heat pump itself. - **Noise.** Modern units sit around fridge level at a few metres. Poor siting, not the equipment, causes almost every noise complaint we are called to. - **Lifespan.** Roughly 15 to 20 years for a heat pump against 10 to 15 for a boiler, assuming annual servicing on either. - **Servicing.** Both need yearly attention. Ours is covered under [servicing and maintenance](/services/servicing-maintenance), and we carry Gas Safe registration alongside MCS, NAPIT and RECC. ## Controls make a bigger difference than people expect Heat pumps reward being left alone to run steadily and punish being switched on and off like a boiler. Zonal control with proper weather compensation lets each room hold its own setpoint while the system stays at a low flow temperature. That is why we fit [smart thermostats and zonal control](/services/smart-thermostats) as part of the design rather than as an afterthought. A well controlled heat pump and a badly controlled one can differ by a fifth on annual running cost with identical hardware. ## So which should you choose? Choose a heat pump if you are off the gas grid, if you are already planning floor work or a renovation, if you can accommodate underfloor heating or larger emitters, and if you want to be ahead of where building regulations are heading. The grant makes the sums work far better than most people assume. Stay with a boiler for now if your property has very high heat loss, no route to improving the emitters and no appetite for insulation work. We will say so at survey rather than sell you something that disappoints, and our [consultancy and design](/services/consultancy-design) service can set out a staged plan to get you there later. Either way, the decision should follow a proper room by room heat loss calculation, not a rule of thumb. That is why underfloor heating quotations come back within 24 hours while heat pump quotations take 3 to 7 days. Installations themselves run 1 to 5 working days, with 2 to 3 days typical. ## Frequently asked questions ### Are air source heat pumps cheaper to run than a gas boiler? It depends on the flow temperature your home can run at. A heat pump paired with underfloor heating at 35 degrees is usually cheaper to run than a gas boiler. The same heat pump forced to run at 55 degrees through undersized radiators often is not. ### Do I need underfloor heating to have a heat pump? No, but it is the ideal partner. Underfloor heating spreads heat across the whole floor area, so the water only needs to be around 35 to 40 degrees, which is exactly where a heat pump is most efficient. ### How noisy is an air source heat pump? A modern unit is roughly comparable to a fridge heard from a few metres away. Siting is assessed during the MCS design so the unit is not placed under a bedroom window or in an enclosed corner that reflects sound. ### Will a heat pump work in a Victorian or 1930s house? Yes, in most cases. What matters is the emitter surface area and the heat loss figure, not the age of the property. Retrofit underfloor heating is often what makes an older Cheshire home work well on a heat pump. ### How long does a heat pump last compared to a boiler? A well maintained air source heat pump typically lasts 15 to 20 years against roughly 10 to 15 for a gas boiler. Both need annual servicing to reach the top of that range. ## Get a straight answer on your property. Book a free survey across Cheshire and South Manchester.
