An air source heat pump extracts free heat from the outside air — even in winter — and uses it to heat your home and hot water. For every unit of electricity it uses, it typically delivers three to five units of heat, making it far more efficient than an oil, LPG or gas boiler.
We handle everything: heat loss survey, system design, installation, commissioning, MCS certification and grant paperwork.
Many heat pump installations are built around a buffer tank or low loss header — a vessel that separates the heat pump's own circuit from the circuit feeding your radiators or underfloor heating. Wherever the system design allows it, we do things differently: we design a single open loop, with a single circulating pump circulating water directly around your entire heating system, with nothing in between.
That matters because a buffer tank or low loss header mixes flow and return water, often forcing the heat pump to run at a higher flow temperature than it actually needs to — which means more electricity for the same heat output. Removing that extra vessel & pump(s) lets the heat pump modulate smoothly, run at the lowest possible flow temperature, and respond directly to what your home actually needs.
Open-loop design demands much more careful design and hydraulic balancing up front — there's no buffer tank or low loss header to hide behind if the hydraulics aren't right. That's exactly why so many installers default to fitting a buffer tank or low loss header on every job, regardless of whether the system actually needs one: it's a safety net that papers over sizing and balancing mistakes, at the cost of your system's efficiency.
We take the harder, better route. Getting a true open loop right is exactly the kind of proper engineering we build every system around — and it's where BECS specialises.
An open loop isn't universally the right answer for every property. In a very small number of cases, a buffer tank or low loss header is still the correct engineering choice, and we'll size and recommend one if the design genuinely calls for it.
Our starting point is always a true open loop, because that's what delivers the best efficiency from an air source heat pump system. We only add a buffer where the heat loss survey and system design show it's genuinely needed — not as a default.
The Boiler Upgrade Scheme (BUS) gives homeowners in England and Wales a grant towards the cost of replacing a fossil fuel boiler with an air source heat pump. As MCS certified installers, we apply for the grant on your behalf — the discount comes straight off your quote.
The enhanced grant window is limited — it ends on 31 March 2027. If you heat with oil or LPG, now is the best time there has ever been to switch.
You may also be able to combine the BUS grant with other incentives from your mortgage provider — click here for more.
