Mains Pressure Hot Water Cylinders in Kent.
Upgrade to high-recovery stainless steel unvented cylinders. Powerful mains-pressure showers across multiple bathrooms simultaneously, engineered specifically for heat pumps.
Technical Excellence & Specifications
Every CPSL installation conforms to rigorous Microgeneration Certification Scheme standards and precision heat loss modelling.
Mains Pressure Showers
Delivers full flow rate to multiple showers and baths at once without weak dribbling water pressure.
3.0m² Oversized Coils
Specially designed large-surface-area heat pump coils for rapid 30-minute full tank reheat times.
Duplex Stainless Steel
Superior corrosion resistance that eliminates internal rust with a 25-year manufacturer guarantee.
Removes Cold Tanks in Loft
Free up valuable attic space by removing old header water tanks and unhygienic cisterns.
Why Heat Pumps Require a Dedicated Cylinder
Standard hot water cylinders built for gas boilers have small 0.8m² heat exchanger coils designed for 75°C boiler water. A heat pump requires an oversized coil (typically 2.5m² to 3.3m²) to transfer heat efficiently at 55°C, ensuring rapid reheat without electric immersion backup.

Lifetime Local SupportFrequently Asked Questions
Everything you need to know about engineering standards, grants, and living with renewable systems in Kent.
help Can I keep my existing hot water cylinder when installing a heat pump?
Standard boiler cylinders cannot transfer heat fast enough from a heat pump. A dedicated heat pump cylinder with an oversized coil is essential and is covered under the £7,500 BUS grant allocation.
help Where can the cylinder be installed?
Cylinders are usually installed in an airing cupboard, utility room, garage, or loft space. Because they are sealed, unvented systems do not require gravity feed.
help Will my shower pressure improve?
Yes, dramatically! Unvented cylinders deliver hot water at full incoming mains pressure, transforming low-pressure gravity showers into invigorating power showers.
help Is there an immersion heater for backup?
Yes. Every cylinder includes an integrated 3kW titanium immersion heater for emergency backup and scheduled anti-legionella cycles.
