Greentherm are suppliers to the Irish market of high quality, custom domestic hot water cylinders, manufactured from 316L marine grade stainless steel. We also supply Jaspi Oval thermal stores and tank-in-tank systems, suitable for tight or irregularly shaped spaces.
Your thermal store, or hot water tank, is the core of a modern central heating system. It will be a part of your home for years to come. It is important therefore, to chose a cylinder that will last.
Poor quality cylinders or tanks may be poorly insulated, causing your system to lose heat, costing you money. They may be made from lower grades of steel that are more susceptible to corrosion or cracking with age. Or they may be fitted with a magnesium anode that requires regular replacement to prevent corrosion.
Replacing or repairing a leaking or damaged cylinder can be an expensive experience, not to mention not having any central heating system or hot water for a period, and the disruption to your home while the repair work is carried out. You cannot afford to buy a cheap, poor quality cylinder.
When it comes to your home, peace of mind is priceless.
Greentherm Cylinders are manufactured from 316L Stainless Steel, a Marine-Grade Stainless steel known for its superb corrosion resistance, toughness under stress and extreme durability. It’s little wonder 316L is the standard steel grade used within the demanding pharmaceutical industry where reliability, integrity, cleanliness and purity must be assured at all costs.
We offer custom cylinders designed and built to meet your exact specification. Greentherm deals directly with the manufacturer, ensuring that your exact specifications are met, while allowing us to supply you a custom cylinder at the same price some retailers will charge for a simple generic tank.
Each Greentherm Cylinder is supplied with 50mm Polyurethane foam insulation, at a manufactured density of 40kg/m3, for outstanding efficiency and thermal performance. All fittings come pre-threaded in 1″ BSP from the factory. A 10 year anti-leak warranty* as standard gives you peace of mind.
No matter your application, your Greentherm Cylinder can be trusted to give years of hassle-free service
Greentherm combined cylinders are an excellent match for low temperature heat sources such as heat pumps and solar thermal. Inside the outer buffer tank there is a marine-grade 316 Stainless Steel domestic hot water cylinder fully surrounded by the heating system water. This ensures a fast recovery of the hot water cylinder without the need for high temperatures as in conventional buffer stores with heat exchanger coils.
We also offer a range of Jaspi GTV Tank-in-Tanks for situations where access may be tight and a flexible, multi-tank solution is required. Indirect hot water coils in Jaspi tanks are flange mounted and can easily be installed later on or replaced if needed. GTV thermal tanks also have connections for electric immersion heaters.
