Frequently-asked Questions
Top Asked
Installation & Repairs
Can WARMHOUSE heat pumps operate in cold climates ?
Answer : Yes, our units are equipped with EVI (Enhanced Vapor Injection) technology, which ensures reliable operation in low ambient temperatures down to -25°C, making them ideal for cold regions.
What is Full Inverter technology and how does it benefit the user ?
Answer : Full Inverter technology enables the compressor and fan motor to operate at variable speeds, adjusting power precisely to the heating or cooling demand. This results in higher energy efficiency, quieter operation, and longer equipment lifespan.
What kind of refrigerant will be used in WARMHOUSE's heat pump ?
Answer : WARMHOUSE heat pumps use eco-friendly refrigerants such as R32 and R290, which offer high energy efficiency and significantly lower Global Warming Potential (GWP) compared to traditional refrigerants.
What size of heat pump do l need ?
Answer : The size of the heat pump you need depends on several factors, including your home size, insulation quality, climate zone, and your desired heating/cooling load. A unit that’s too small may not meet demand, while one that’s too large could cycle inefficiently.
We recommend consulting with a professional HVAC installer who can perform a heat load calculation to determine the optimal capacity. WARMHOUSE offers a wide range of models to match various needs, from compact residential units to high-capacity Full Inverter systems for larger homes or commercial spaces.
Why should l choose a heat pump instead of an electric heater ?
Answer : Unlike electric heaters that convert electricity directly into heat, heat pumps transfer heat from the air, making them far more energy-efficient. A high-performance heat pump—like those from WARMHOUSE—can deliver up to 4–5 times more heat energy than the electricity it consumes.
Additionally, modern Full Inverter heat pumps offer quiet operation, precise temperature control, and year-round heating and cooling capabilities. Over time, they lead to significant cost savings, lower carbon emissions, and a more environmentally friendly lifestyle.
What does SCOP mean and why is it important ?
Answer : SCOP (Seasonal Coefficient of Performance) measures the efficiency of a heat pump over an entire heating season. A higher SCOP indicates better seasonal energy efficiency, leading to lower operating costs for the user.
How quiet is a WARMHOUSE heat pump during operation ?
Answer : Thanks to our low sound level design, including inverter technology, acoustic insulation, and optimized fan blades, our heat pumps operate as quietly as 38–42 dB(A) — comparable to a home refrigerator.
What are the typical application scenarios for WARMHOUSE heat pumps ?
Answer : Our heat pumps are suitable for domestic hot water, space heating and cooling, swimming pool heating, and even commercial projects. They integrate seamlessly into residential homes, villas, apartment buildings, and light commercial properties.
How energy-efficient are WARMHOUSE heat pumps ?
Answer : Our products achieve Energy Efficiency Grade A with SCOP values up to 8.76, meaning that for every 1 kWh of electricity consumed, up to 8.76 kWh of heat can be produced—offering maximum efficiency and cost savings.
What is the expected lifespan of a WARMHOUSE heat pump ?
Answer : With high-quality components, anti-corrosion protection, and intelligent control systems, WARMHOUSE heat pumps are designed to last 10 to 15 years or more under normal operating conditions and regular maintenance.
What is the difference between On/Off and Inverter heat pumps ?
Answer : On/Off units run at full power until the desired temperature is reached, then shut off. Inverter heat pumps, like WARMHOUSE’s Full Inverter models, modulate output continuously, maintaining steady temperatures while using less energy and reducing wear and tear.
What kind of maintenance do heat pumps require ?
Answer : Heat pumps require minimal maintenance. It is recommended to check filters, coils, and electrical connections annually. For optimal performance, we also advise professional servicing every 12–24 months.
