Does an Intergas boiler have a three-way valve? No, and this is what it has instead

Short answer: no. The Intergas Kombi Kompakt HRE does not have a three-way valve. Heating water and tap water flow through a single patented two-in-one heat exchanger, so the boiler switches between heating and hot water without a valve. If you are looking for a "three-way valve for your Intergas", the problem usually lies in a different part.

Why an Intergas HRE has no three-way valve

In most combi boilers, a three-way valve sends the hot water either to the radiators or to a separate domestic hot water heat exchanger. Intergas chose a different design: in the heat exchanger of the Kombi Kompakt HRE, the heating circuit and the hot water circuit run together through one block, separated by a double wall. As a result, no diverter valve is needed, which removes a part that is a well-known source of faults in other brands.

This applies to the well-known HRE versions such as the 24/18, 28/24 and 36/30. If you have a different Intergas model, check the parts list for your appliance on Intergas parts by appliance; daar staat precies welke onderdelen erin zitten.

Hot water or heating not working properly: where is the problem?

Because there is no three-way valve, on an Intergas HRE you look at the parts that are fitted. Which part it is will be determined by an installer; the boiler often shows a code itself. The meaning of each code is listed under the Intergas fault codes.

• Heat exchanger: the heart of the boiler, for both heating and hot water. Limescale or dirt causes less hot water or noise. See Intergas heat exchangers.
• Pump: no circulation, no heat. See Intergas pumps.
• Temperature sensors (NTC): measure flow, return and hot water; a faulty sensor gives incorrect temperatures or a fault code. See Intergas temperature sensors.
• Servicing: many complaints disappear after a service. See Intergas service kits.
