How It Works

Modern heating that pays for itself

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.

  • Lower running costs than oil, LPG and direct electric heating
  • Massively reduced carbon footprint
  • Heating and hot water from one quiet, reliable unit
  • No fuel deliveries, tanks or flues
  • Long lifespan with simple annual servicing
  • Works with radiators and underfloor heating

What Sets Our Installs Apart
Our Design Philosophy

What is an open-loop heat pump system?

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.

  • Higher coefficient of performance (COP) — less electricity for the same heat output
  • No mixing losses from a buffer tank or low loss header
  • Smoother modulation and fewer on/off cycles
  • Less components to install, maintain and potentially fail
  • Full weather compensation benefit, since the heat pump sees the real system temperature directly

Why Many Installers Default To Buffers

Optimise, not Compromise

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.

Is It Right For Every System?

When a buffer tank is still the right call

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.

Boiler Upgrade Scheme

Government grants of up to £9,000

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.

£7,500 Standard BUS grant for eligible homes replacing a fossil fuel heating system
£9,000 Enhanced grant for off-gas-grid homes heated by oil or LPG — available 21 July 2026 to 31 March 2027

Are you eligible?

  • You own the property (home or small non-domestic building) in England or Wales
  • You're replacing a fossil fuel system (oil, LPG, gas) or direct electric heating
  • The heat pump is installed by an MCS certified installer — that's us
  • For the enhanced £9,000 grant: your property is off the gas grid and currently heated by oil or LPG

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.
