Whether you require a full system design or simply an update/upgrade to your existing one, you are in the right place.
With our extensive industry experience we are capable of working on all types of heating and plumbing systems, meaning you can have peace of mind knowing that any issue you may have can be resolved in a time and cost effective manner.
Types of System
Heating:
Open Vented: With a Feed & Expansion Tank located higher up in the property, this type of system has been utilised for many years and is often found alongside a similar set up on the hot water side. Due to the modernisation of properties as well as the increased knowledge within the industry many of these systems are being upgraded to unvented.
Pressurised: A closed circuit style system that involves using a fill point, usually known as a filling loop, in order to ‘top up’ the system pressure. Many modern boilers, such as combi boilers, utilise this setup due to the increased efficiency provided by a pressurised system
Open Vented
This system uses many different parts to heat the water. It consists of a hot water cylinder, a cold-water storage cistern (tank), special pipework (known as an open vent pipe), and a heat source to heat the water. 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. The water is heated via a coil (heat exchanger) from a boiler. This is done because there is a set of radiators connected to the boiler, in this case water in the central heating system slowly becomes contaminated by iron residues from the radiators which would make the hot water unusable for washing.
Instantaneous Hot Water Heating Systems
This method involves using gas or electricity to heat the water to a useable temperature without the need to store the water.
The most common method to heat water is the use of a combination boiler, this type of boiler works by using the circuit that powers the central heating and diverting it to another ‘water to water’ heat exchanger (heat swapping). This part swaps out the heat from the heating water to the hot water parts of your home.
Unvented Hot Water Systems
These systems are far more complicated and have many more parts to them but do allow near mains pressure hot water supply. They are designed to do away with the storage cistern and operate at a much higher pressure than the open vented system.
