Ipe-Peite
A heat pump and gas boiler working together
No need to buy two new systems
Ipe-Peite’s Lahti site introduced a hybrid heating system combining an air-to-water heat pump with gas. The heat pump provides around 70% of annual heat demand, with the existing gas boiler supplying the rest.
The solution commissioned in 2019 aimed to reduce heating costs by around 20–30%. The original account estimated a reduction of around 70% in heating emissions and around 50% in purchased energy.
The existing gas boiler stayed in use
We proposed a hybrid system that retained the gas boiler for very cold weather and demand peaks.
“What was good about Auris Energia’s proposal was that we could use the old gas boiler for demand peaks, however cold it got. We did not have to buy two new systems.”
Jyrki Lindblom, owner and Chair of the Board, Ipe-Peite
The heat pump was connected directly to the existing heat distribution system, with no visible changes inside the property.
The heat pump’s automation also controls the gas boiler to prevent unnecessary simultaneous heating.
Under the service model, the customer pays for the heat used and Auris is responsible for operating and maintaining the equipment as agreed.
A pump sized for the site
Heat pumps are often sized according to a site’s peak technical demand. At Ipe-Peite, sizing was based on actual annual heat consumption.
The old ventilation system had a demand of around 200 kW and the gas boiler had a capacity exceeding 300 kW. The new heat pump was sized using the site’s actual annual consumption.
Sizing by peak demand would have resulted in a much larger heat pump. The approach used led to a 63 kW unit.
Straightforward to acquire and use
Because we supply heat as a service, the customer does not need to select, size, install or adjust the equipment.
“I received a system offer in August, and installation began in October and took three weeks. Our production continued without interruption throughout.”
Jyrki Lindblom
The system was commissioned in November 2019.
“The temperature in the hall has been optimal. If purchased energy consumption stays low, things will go well.”
The heat supply agreement made in 2019 was for five years. It included the option to continue the service or purchase the equipment at the end of the term.
The site
Ipe-Peite manufactures made-to-measure PVC products in Finland, including door curtains, protective covers and tarpaulins for trucks. The company has operated for over 40 years.
The Lahti site has a production hall of around 1,600 m² and 8.5 metres in height, plus 200 m² of offices. Large doors accommodate a truck and full trailer; opening them creates brief peaks in winter heat demand.
The premises previously used a relatively new conventional gas boiler. It worked well, but Jyrki Lindblom, who bought the company in 2018, wanted to reduce heating costs further.
