IMPORTANT Under no circumstances should the system be operated
without the heating PRV fitted and working correctly.
4-4.5 Heating PRV Discharge Pipe
The outlet from the heating PRV must be piped using 15mm copper pipe to the tundish
then to a visible position outside the dwelling. The pipe must have a continuous fall and
ideally be terminated over a drain.
The heating PRV may be plumbed to the hot water system TPRV discharge prior to the
Tundish, see fig. 4-4a.
The PRV discharge must comply with Building Regulations G3 refer to pages 40-42.
IMPORTANT Scalding water and steam can be emitted from the
discharge pipe. Position the discharge so there is no hazard to property
or people (especially children).
4-4.6 Heating System Expansion Vessel (red)
Maximum charge pressure
Pre-charge pressure
Capacity
An expansion vessel and mounting kit is supplied, this is suitable for systems with a
static head of up to 5 metres. If the static head is greater than 5 metres the charge
pressure of the expansion vessel will need to be increased. Increase the pressure using a
standard car tyre pump and pressure gauge when the system is empty (zero pressure).
Expansion vessels are suitable for systems requiring a maximum expansion of 7 litres as
detailed above. For systems requiring more expansion a second expansion vessel will be
required. BS7074 Part 1 includes information on this requirement.
Clearance is required on top of the vessel to access the pressure valve.
4-4.7 Filling Loop
A Filling Loop comprising a flexible hose, double check valve and an isolating valve is
supplied for filling and topping up the system.
