FAQs
How quiet are your whisper-quiet heat pumps, and what keeps the noise so low?
Our latest-generation units operate at 45–50 dB(A) when running at full capacity—roughly the volume of a library and far below the 60–70 dB(A) of a traditional outdoor condenser. We achieve this using variable-speed inverter compressors, insulated acoustic enclosures, slow-turn axial fans, and rubber anti-vibration mounts. In most garden or side-passage installations you will barely notice the system over normal background sounds in Lancing.
Will a heat pump work efficiently in Lancing’s coastal climate?
Yes. Lancing enjoys relatively mild winters (average 2–8 °C) and cool summers, conditions that are ideal for air-source heat pumps. Our models carry SCOP ratings up to 4.8, meaning they deliver up to 4.8 kW of heat for every 1 kW of electricity used. Even on frosty mornings the inverter adjusts speed to maintain efficiency, and a factory-installed coastal protection coating prevents salt-air corrosion.
Can one system provide both heating and air-conditioning for my home?
Absolutely. All our whisper-quiet units are reversible air-to-air heat pumps that heat in winter and switch to high-efficiency cooling in summer. You control both modes from a single wall controller or mobile app, and the system automatically defrosts and changes refrigerant flow direction as required. This dual-function approach eliminates the need for separate boilers and air conditioners.
What size heat pump will I need for my property in Lancing?
Sizing depends on floor area, insulation levels, window type, and desired indoor temperatures. As a rule of thumb you need 50–70 W of heating output per square metre, but we always carry out a free on-site heat-loss survey with SAP calculations to confirm. For example, a well-insulated 3-bed semi (~90 m²) typically uses a 5 kW outdoor unit with two or three indoor air handlers.
How long does installation take, and will it disrupt my home?
Most domestic retrofits take 1–2 days. Day 1 we mount the outdoor unit on a vibration-isolated pad, run insulated refrigerant lines through a 75 mm core hole, and fit indoor air handlers. Day 2 we pressure-test, vacuum, and commission the system, then programme your controls. Because the outdoor unit sits outside and all pipework is pre-insulated, internal disruption is minimal—no ripping up floors or chimneys like a boiler swap.
What maintenance is required and how much will the system cost to run?
Routine maintenance is simple: rinse the outdoor coil with a hose every six months, clean or replace indoor filters quarterly, and book an annual service (approx. £120) where we check refrigerant charge and electrical connections. Running costs vary with tariff, but at today’s average electricity price of 28 p/kWh and a SCOP of 4, you pay roughly 7 p per delivered kWh—around 35 % less than mains gas and up to 60 % less than LPG or direct electric heating. Eligible Lancing homeowners can also claim up to £5,000 through the Boiler Upgrade Scheme to offset purchase costs.
