Daikin Heat Pump In Brief:

Daikin are a world-renowned manufacturer of air-conditioning systems. They have a long-established heat pump product line, which includes domestic air source units. Their wall-mounted and floor-standing heat pumps display a distinctive and stylish aesthetic.

These are a good mainstream product, although more expensive than some brands. The Altherma range is noted for functioning well in cold temperatures, so could be a prime choice if you live in one of the colder parts of the UK. Fortunately there are government grants available to offset some of the costs of installing a heat pump, which should be more efficient than a conventional gas boiler, thus saving on heating bills.

Warranties are between five and ten years, depending on the particular product.

Daikin Company Overview:

Daikin is the world’s leading air-conditioning unit manufacturer. A Japanese company, it was founded way back in 1924, and sells a massive amount of heating and refrigeration products annually. Active in over 170 countries, Daikin is the kind of market-leading brand you can’t go far wrong in purchasing. They have a justly-deserved reputation for innovation, excellent engineering and quality-control, with global sales and service backup. Think of them as the Toyota of air-con.

Although Daikin has been researching heat pump technology since the 1950s, it was in 2009 that it started selling residential heat pumps, initially to the Chinese market.

Why Install a Daikin Heat Pump?

Essentially heat pumps draw residual heat from the air, the ground, or water. Most homes in the UK are using air-source heat pumps as they are the simplest to install and run. 

Heat pumps are a low-carbon green alternative to other forms of heating such as gas, electricity and oil. They typically output three times more heat per unit of energy input. Now that power bills are rising rapidly, they can help households reduce energy costs by up to 40%.

They are a good investment: the system can pay off in as few as five years, which is much better than installing oil or LPG heating. If you already are generating some of your own electricity, a “prosumer” (for “producer/consumer”), then you can fit a heat pump to make your system more efficient. However it is not necessary to have solar panels on your roof to benefit from installing a heat pump. They can replace conventional boilers, as they are more efficient and generally have greater reliability from fewer moving parts.

Daikin Heat Pumps are approved by the Microgeneration Certification Scheme (MCS) which enables access to various grants and funding schemes which can help to reduce the total cost of installation.

Daikin Heat Pump FAQs

Q: What does a “heat pump system” actually consist of?

A: There are normally three parts to a heat pump system: the outdoor unit, which transfers heat from the air to its indoor companion: a boiler-like device, which raises the temperature of water to generate the heating, and a control unit, nowadays this is often an app on your phone.

Q: Can you attach a heat pump to existing radiators?

A: Heat pumps can be attached to most radiators, so they can be retrofitted into an existing home-heating system without much disruption.

Q: Is there funding available to reduce the cost of the system?

A: Currently there are grants available for heat pump installation but they depend on where you are in the UK. Government funding is prone to abrupt changes of policy so please contact ESE Group to discuss what is available now.
