Heat distribution room maintenance saves both time and energy!


Maintenance of a district heat distribution room saves residents money. When the equipment works as it should, energy doesn’t go to waste. District heat itself is a carefree choice since it doesn’t actually require the residents of a property to do anything. However, there are a few things residents should now about their heat distribution centre.

“It’s useful to know roughly what equipment forms part of the heat distribution centre and what each device is for. At the very least, you should know the location of the property’s main shut off valves, which means the district heat shut off valve and main water shut off valve,” says Sami Karjalainen, HVAC engineer, Heating Services at Oulun Energia.

Karjalainen often hears that it would be better not to touch the district heat system or its controls at all. He himself encourages customers to learn about their system and how it works.

“The control functions of newer heat distribution systems in particular are clear. Some controls also warn users that they are perhaps making the wrong choices,” Karjalainen assures.

Chilly indoor air or abnormal domestic water temperature indicates a fault

A district heat system has a useful life of 20-25 years. Rather than infinitely repairing a system that has served faithfully for years, it makes sense to replace it with a new, technically and more energy efficient one. System faults are noticed when a home feels cold or when the domestic water temperature is not as it should be. The most common reason for a cold home is because of too low pressure in the heating network.

“It’s always worth checking the pressure ahead of the actual heating season and also regularly during the heating season,” Sami Karjalainen advises.

Poor cooling of the district heat, for example, indicates a fault in the system. Cooling means the temperature difference between the district heat heating supply and return water. When the equipment works as it should, the supply water reaches the property from the district heat power plant, circulates in the heating system and returns cooler through the return pipe back to the plant for reheating. The more it cools the better the heating system works.

"When cooling is poor, the water flows through the system and returns without releasing energy,” says Karjalainen.
