01
Cold weather does not end spa season
Enhanced Vapour Injection supports operation down to -25°C ambient temperature, so the heat pump is designed for year-round use rather than fair-weather duty.

iNHEAT 7kW SpaLine EVI Heat Pump for Hot Tubs and Swim Spas
LOWER-COST, YEAR-ROUND SPA HEATING
Keep the water hot without asking a 2kW heater to do all the work
The iNHEAT 7kW SpaLine is built for the temperatures a hot tub actually needs. Full Inverter control matches its output to demand, while EVI technology keeps it operating when the weather falls as low as -25°C.
7kW heating output
10–40°C water range
<32dB at 10 metres
FULL INVERTER TECHNOLOGY
It works as hard as the water needs, then quietly eases back
A conventional electric heater is a blunt tool: it switches on at full power and switches off again. SpaLine continuously adjusts compressor output to suit the water temperature and conditions outside.
That steadier approach means less wasted energy, a more stable set temperature and less stop-start strain on the compressor. Your actual saving will depend on the spa, cover, insulation, weather and electricity tariff, but the principle is refreshingly simple: buy less heat from the socket.
WHY SPALINE
The useful technology is built in, rather than sold back as an extra
EVI cold-weather performance, reversible heating and cooling, integrated WiFi and quiet-running control are all part of the unit.
02
Your set temperature is in your pocket
Integrated WiFi connects to the Smartlife app, letting you check the water temperature, adjust settings and manage the unit without walking out to the spa.
03
Quiet enough for the garden you bought it for
Published sound pressure is below 32dB(A) at 10 metres. Silent mode reduces output when maintaining temperature matters more than rapid recovery.
04
Heat in winter, cool when summer gets ideas
Reversible operation gives a 10–40°C water set range. Keep the spa at bathing temperature or cool the water for a fresher summer soak.
CONTROL WITHOUT FUSS
Choose speed, silence or let the heat pump decide
AutomaticSelects heating or cooling to hold the chosen water temperature.
BoostRaises output when you want to reach the set temperature sooner.
Silent / EcoRuns more gently when efficiency and lower sound matter most.
Heating / CoolingGives you direct control over the job the unit is doing.
BEFORE YOU ORDER
A compact upgrade, provided the flow and pipework are right
The SpaLine connects to a suitable hot tub or swim spa circulation circuit, normally through a bypass arrangement. The bypass kit is sold separately.
- Water flow: optimum flow rate of 2m³/h
- Connections: 1-inch male with Ø32–38mm pipe compatibility
- Position: stable, level base with at least 300mm clear at the sides and rear and 1.5m clear in front
- Electrical: 220–240V single-phase, 50Hz supply; have a qualified electrician confirm protection and connection requirements
- Insulation: insulate the hot tub, circulation pipework and cover to reduce heat loss
- WiFi: a usable 2.4GHz signal at the unit if you want app control
Compatibility depends on your spa’s circulation, control system and pipe layout. If you are unsure, call us on 0330 043 0870 before ordering and we will help you check the setup.
