What is a Santon Premier Plus?
The Santon Premier Plus is a purpose designed unvented water heater. The unit has a stainless steel inner vessel which ensures an excellent standard of corrosion resistance. The unit is supplied complete with all the necessary safety and control devices needed to allow connec- tion to the cold water mains.
Is unvented cylinder direct or indirect?
For example, a direct unvented cylinder utilises electricity to heat the water using immersion heaters, whilst an indirect unvented cylinder utilises gas from a boiler to heat the water.
What is an indirect unvented cylinder?
Indirect Unvented Cylinders Indirect Cylinders rely on external appliances to apply the necessary heat to the cylinder – this in turn generates the hot water that is stored, or also used as a backup if the main heat source fails.
Do unvented cylinders need registering?
Under Building Regulations, it is necessary to notify Local Authority Building Control (LABC) of the installation of both unvented and vented hot water cylinders. Contact Gas Safe Register to confirm you have a Hot Water qualification.
How does a Pressurised hot water system work?
A thermal store is a vented pressurised water tank. Unlike unvented systems where the hot water in the tank is sent to the taps, the thermal store heats water that is already in the tank and then uses the heat from that water in the tank to transfer heat to incoming cold water.
Can I use an indirect cylinder as a direct cylinder?
This can be used in a direct system but a direct cylinder cannot be used in an indirect system without modification.
What is direct and indirect cylinder?
Open vented hot water systems There are two types of open vented hot water; direct heating and indirect heating. • Direct heating – the water is heated directly from the heat source either by an immersion heater or by the boiler. • Indirect heating – the central heating and the hot water are separate.
What’s the difference between a direct and indirect cylinder?
Direct and Indirect A ‘direct’ cylinder is heated via an electric immersion and does not work with gas, oil or heat pump systems. An ‘indirect’ cylinder has coil running through the cylinder. The heated coil imparts its heat onto the fresh (potable) water in the tank that is used for washing or showering.
What must be established before installing an unvented hot water cylinder?
Before you have an unvented system installed, you need to contact your local Building Control Department to tell them. This is because the property may need some pressure relief pipework and valves to be installed which will vent out of the building.
