Sayfayı YazdırThe immersion heaters should not be required during the solar season, although the top one
can be wired to a switched spur for any essential top up.
The immersion heaters should be set at 75°C.
Note:The immersion heater supplied is fitted with a thermal cut out.This is an essential
safety requirement,and immersion heaters without thermal cut outs must not be used.
As it is a thermal store, thermal disinfection is not needed.
Some degree of experimentation in operation is likely as different systems will have different loads
placed upon them.
Solid fuel systems are ideal – biomass, wood burning stoves or cookers can all be connected. It is
possible to meet sealed system G3 requirements of Building Regulations by using the fully
assembled SFUTS where the wiring and plumbing is provided.
Ancillary input is generally of an intermittent nature – for example a wood burner is usually only lit
during certain periods of the day and should not be used at all in warmer weather where solar may
be more appropriate. It is recommended that a gas/oil boiler is used with any intermittent heat
source. Whilst it is possible to use electricity it can be expensive and off peak tariffs are preferred.
Heat pumps are an option but it must be understood that the store operates at 75°C. It is essential
that a heat source such as a gas or oil boiler is used for top up and that they achieve at least 75°C
output. Each input has a dedicated thermostat so 75°C is easy to achieve with a wood burner for
example and will result in substantial savings on gas or oil bills.
VENTED OR SEALED SYSTEMS
The Universal can be vented or sealed. If it is vented the top connection of the tank is where
the vent pipe (22mm) should be installed and the feed can be into the drain point (15mm) or a
negative point on the system.
A vented version will not have the relief valve, the thermal safety valve or pipework and tun
dish fitted.
The relief valve is there in case of over pressurisation in a sealed system. It is not an over-
heat protection device. It is recommended that another pressure relief valve is fitted in open
circuit as additional over pressure protection in a sealed system.
Always remember when calculating expansion on a system to include store volume. See page 8.
It is possible to install another fuel source with a boiler in a sealed system. Control is the key,
along with the appropriate levels of safety. Gas or oil boilers are controllable devices and hi-
limit thermostats on the store will suffice along with the relief valve as these appliances have
their own in built protection.
Some solid fuel appliances have built in protection where heat exchangers can be water cooled for
example, and these are preferred in sealed systems. However, it is possible to use other types and
we would refer you to the next section showing our pre wired pre plumbed SFUTS.
