What Coolhouse OÜ does

Coolhouse OÜ is an Estonian private limited company founded in 2007, headquartered in Viimsi vald, Estonia, that designs, distributes, and supplies geothermal and air-to-water heat pump systems, water tanks, and industrial refrigeration equipment across the Estonian and Finnish markets. The company's core product portfolio spans three series: the GP (Green Power) monoblock and split heat pumps in R32 and R290 refrigerant variants (6-90 kW), the ES (Energy Save) monoblock and split systems with integrated domestic hot water tank options, and the AW30/AW45/AW90 commercial series supporting cascade configurations up to ~1.3 MW aggregate capacity. All products feature inverter technology with electronic expansion valves, WiFi connectivity via native Apple/Android applications, and Smart Grid external control support, with energy class ratings of A++ to A+++ and SCOP values of 3.90-4.98. Beyond heat pumps, the company distributes complementary hardware including stainless steel buffer and DHW tanks, wall-mounted fan coils, LFP battery energy storage systems (14.3 kWh), and industrial refrigeration equipment (Simag/Howe ice machines up to 10 tonnes/day, cold storage rooms, and 20ft/40ft refrigerated containers).

The company operates a unique in-Estonia turnkey geothermal drilling service using Rehau borehole probes (50-200 m depth, up to 10-year factory warranty), which differentiates it from pure equipment resellers. Compressors are sourced from Mitsubishi, Panasonic, and GMCC, while circulation pumps are sourced from Wilo and Grundfos. The go-to-market is primarily direct sales through an Estonian-language website with Finnish translations, a downloadable PDF product catalog, phone/email quoting, and a physical warehouse pickup option in Viimsi. Payment is accepted via credit card and Swedbank bank transfer, with all prices inclusive of the 24% Estonian VAT rate. Customer segments span residential homeowners (B2C primary), commercial/industrial buildings (korteriühistu, production halls), food processing and cold chain logistics, and solar prosumers seeking battery storage for grid arbitrage. The company also sells regulated refrigerants (R410A, R404A) to certified buyers under EU 573/2024. No revenue, headcount, funding, or ownership data is publicly disclosed in the available sources.
