Installation of central heating systems is quite complicated and needs to be done by trained professionals only, as failure to comply with certain installation safety rules can lead to fireplace or central heating system damage, and even personal injury. Incorrect or negligent installation can lead to leaks or air chokes in the system which prevent proper heat distribution and various other system problems.
Simplistically put, Hydrofire Cape Town typically installs “closed system” central heating system types where cold water heated by the boiler stove fireplace is circulated through radiators in bedrooms, effectively distributing heat from the fire throughout the home. Essentially the heated water is pushed by a circulation pump from the boiler stove to a distribution manifold. It is very important that an inline filter is installed before the circulation pump entry. This inline filter protects the pump impeller from hard particles. It is also very important that shut off valves be placed on each side of the pump and filter to accommodate filter cleaning and pump service without having to drain the water from the entire system. Once the hot water from the stove reaches the distribution manifold (sometimes situated in the roof cavity with existing builds) it is split into 4-8 pipes going into different directions in order to supply hot water to the various radiators. There are specific guidelines that should be followed for correct piping installation to prevent air-locks and other problems.
Hydrofire installs various parts to ensure correct installation:
· Automatic Air Relief valves · Temperature safety valve – an emergency cooling valve which opens up to cool the fireplace upon reaching 95’C to prevent boiling. · Pressure safety valve -An important component which prevents over-pressure and acts as a safety in case the temperature safety valve fails to activate. · Expansion Vessel – this is to accommodate for the constant thermal expansion and contraction of the water. · Thermal Electrical Switch – used to start the circulation pump when the boiler stove water gets warm; · Temperature and Pressure Gauges – also need to be installed properly to give accurate reading
We also offer various other more complex parts and control systems to better protect the boiler stove and to more accurately control the system. Please note that central heating systems installation is not a simple task- in fact it’s a specialised career in Europe- so please do not attempt a DIY installation unless you have been properly trained. Rather turn to our team of experts to help you set up a safe and effectively central heating system that will help you get the most out of your boiler stove fireplace.
