Calesco Waterbed Heater, 8" & 9" Deep-Fill: Solid-State 325W
$164.95
This is a 325-watt solid-state waterbed heater from Backer Heating Technologies of Sweden (Calesco), built for 8" and 9" deep-fill softside waterbed mattresses. The etched copper-foil pad spreads heat evenly across the mattress, while a precision electronic thermostat holds your water temperature within about one degree so the bed stays at the comfort level you set. It's a good fit for anyone replacing a heater on a deep-fill bed who wants quiet, steady warmth and a long-lasting, low-energy unit.
Best for 8" and 9" deep-fill softside waterbed mattresses (not for 3.5" tube beds).

A filled waterbed spreads its weight across the whole frame and deck, so a normal residential floor handles it fine. If you're on an upper floor or unsure, call us and we'll talk it through.
Softside beds set up much like a regular mattress; hardside beds fill inside the frame. We include setup guidance and our team walks you through fill, heat, and conditioning — we do it every week.
Yes — a heater keeps the bed at a comfortable temperature and conditioner protects the vinyl and keeps the water clear. See “Complete your system” below for the matched parts.
Softside looks and sits like a standard bed (foam rails, no exposed frame); hardside is the classic deep-fill feel in a wood frame. Read our waterbed guides or ask us which fits your room.
