Heatese V Combi Boilers

We often get asked how Heatese compares to a Combi boiler. Here we will attempt to explain the differences and similarities.

To begin with we might as well get to the most basic part of the comparison and that is the size of the units. You are probably aware that a combi boiler can fit nicely into a cupboard in your house or garage. Heatese boiler system will not do this. To be ale to generate the Energy Savings we offer the Heatese not only has the burner and several heat exchangers it also includes a buffer tank to store the hot water. Ideally a Heatese gas or oil boiler would be installed on the outside of the building or in the garage or plant room. If there is one benefit, when you choose to install Heatese, you may free up a cupboard in your home!

The Heatese Boiler System Inner Workings

One of the main advantages of a combi boiler is the ability to deliver hot water on demand. The disadvantage of this is it can be relatively energy intensive to maintain this hot water whilst you shower or bath. Heatese offers an immediate supply of hot water but without the same level of energy expenditure; due to the built-in buffer tank which can supply a heat exchanger immediately. The Heatese Buffer tank is so well insulated, that even if you switched off the boiler for 24hrs you would only lose 5 degrees of Heat.

A big question for people is the running cost of the boiler and how the two compare It can be tricky to compare the energy saving as there are many different types of combi boilers available on the market. What we can do is carry out a survey to calculate the anticipated energy savings we would expect you to achieve if you installed the Heatese Boiler.

How the Boilers Work.

Heatese and Combi boilers work in very different ways

Typically a combi boiler in simple terms the fuel supply comes into the boiler and is directed to the burners in the boiler

The burners are activated by messages from the valves in both the central heating and hot water systems in your home. If a valve (tap) is turned on which asks for hot water to a shower for example, the open tap allows the water to flow.

The flowing water in the boiler runs over something called a paddle switch which turns the burners on in the specific part of the boiler which heats the water for the taps (The Domestic Hot Water system)

 In some boiler model heat is stored in a heat exchanger, a small compartment within the boiler, when (for example) the central heating is in full flow, there is a small reservoir of hot water in the heat exchanger allowing a more instantaneous feed the hot water taps for the  domestic hot water system.

The combi boiler uses direct heating from the burner to heat the water and uses high volumes of energy to achieve the requires temperature as this is an instant requirement

The Heat exchange in a Combi boiler is split in two halves – one for the hot water and one for heating both with their own thermostat..

Heatese differs greatly from this as it uses indirect heating using the hottest part of the burning gases  to heat a copper heat exchanger placed at a strategic point in the patented chamber. Flue gases leave the chamber and pass through a series of further heat exchangers to extract every bit of heat possible from the flue gases.  

When you require hot water Heatese simply uses its internal buffer tank to supply this water as previously stated it is so well insulted even if you turned off your boiler for 24hrs it would still supply hot water into your home.  This water is heated via lower pressures and over a slightly longer period that also prevents needless cycling.

On hot water request this can be drawn from a heat exchanger coupled to the buffer tank or in the case of the central heating this is taken directly from the buffer tank.

Waste heat from the heat exchangers is also recycled into the buffer tank

Heatese is always on and always Saving.

Heatese boilers are available to run on Gas, LPG and Heating Oil and can be installed in both domestic and commercial applications
