Hot water cylinders & calorifiers — designed and manufactured in Greater Manchester
Durable stainless steel cylinders, low-impact insulation and ranges built for heat pumps — made in our own factory in Greater Manchester.
The most sustainable cylinder is one that doesn’t need replacing.
Our domestic cylinders are made from duplex stainless steel, which resists corrosion and scale — particularly in hard water areas.
25 year guarantee on stainless steel unvented cylinders up to 300 litres, subject to annual servicing.
Register a warrantyStainless steel is a recyclable material, so a cylinder’s vessel doesn’t have to become waste at the end of its life.
Keeping stored heat in means less energy used to reheat it.
Our unvented cylinders use polyurethane foam insulation made with a CO₂ blowing agent: its global warming potential is less than 5 and its ozone depletion potential is zero.
We test for heat loss, performance and lifecycle in our own test room in Manchester, and every cylinder’s ErP class is published on its datasheet.

Climacyl heat pump cylinders have large 2–3 m² coils sized for heat pump flow, from 120 to 500 litres.
ClimacylPre-plumbed heat pump packages for LG, Mitsubishi Ecodan and Samsung systems, with integrated buffers.
Pre-plumbed cylindersBuffer vessels stop heat pumps, boilers and chillers short cycling, helping them run efficiently.
Buffer vesselsTwin coil cylinders and thermal stores combine heat sources such as solar thermal, heat pumps and solid fuel.
Thermal storesDesigned, welded and tested in our own factory in Dukinfield.
Cylinders for UK projects are built here rather than shipped from overseas, and we control quality under a BSI-audited ISO 9001:2015 system.
AccreditationWe are a registered WEEE producer and manage electrical equipment through the Beyondly compliance scheme.
AccreditationExtending the life of existing plant avoids scrapping it early.
Genuine spare parts and components are available for our cylinders.
Spare partsReducing the footprint of the factory itself.
In 2015 we installed a 16 kW solar PV system to help power the heavy plant used to fabricate our cylinders.
Reducing our own carbon emissionsFrom 10 litres to 10,000 litres, our Manchester team designs, manufactures and tests every vessel in-house.
