Why should I use a Heat Pump?

Why should I use a Heat Pump?

Heat Pumps have gained in popularity since the changes in building regulations 2011. There are many reasons for this. While heat pumps meet all current and future NZEB (Near Zero Energy Building 2020) regulations, they are also the most economical way of heating your house as well as reducing CO2 emissions. By fitting a heat pump you are future proofing your home as fossil fuel options such as oil & gas boilers will be soon outlawed by government.

How efficient is an air to water heat pump in comparison to other heating options?

How efficient is an air to water heat pump in comparison to other heating options?

An air to water Heat Pump is the most efficient way by far to year your house. A well designed air to water heat pump system is 400% efficient. What that means is for every 1 kilowatt of electricity supplied to the heat pump, will generate the equivalent of 4 kilowatts of usable heat to your home. In comparison, Oil and gas boilers will only achieve 80 to 90%. Stoves will score even worse as these come in at approx. 40% at best.

What is an air to water heat pump?

What is an air to water heat pump?

An air to water heat pump collects the heat from the outside air and through a refrigeration cycle, generates heat for our homes. There is liquid in the heat pump which will boil at -40 degrees Celsius. (Water boils at 100 degrees Celsius). This liquid changes into a gas when boiled. This gas is compressed. When you compress a gas, the temperature of the gas increases which is then used to heat our homes and hot water for our showers.

What is the difference in heat pumps (mono VS Split)?

What is the difference in heat pumps (mono VS Split)?

A Monobloc heat pump...

...is a single unit heat pump located outside your home. It heats your water outside the dwelling and sends in the warm water to heat your home. These monobloc heat pumps would be slightly cheaper to buy and install. However, the big drawback is that you are heating your water outside the house which, in winter, the heat pump will have to work harder and therefore will be more expensive to run as the water may cool down before it enters your house.

A Split heat pump...

...works differently to a monobloc heat pump mentioned above. A split heat pump, has the condenser (this collects the heat from the air) and sends in the heated gas (not water) into your house to what we call the indoor unit. (This is where the hot gas heats your water). The indoor unit comprises of many parts but the most important is it houses your hot water cylinder (water for your showers and taps). As all the heated water is contained within the building, the split systems would be considered cheaper to run.

What is an outdoor unit?

What is an outdoor unit?

An outdoor unit is called the condenser. This primarily collects the heat from the air which boils the gas within the unit. This heated gas in turn, heats the water that is heating your house as well as the water for your showers. 

What is an indoor unit?

What is an indoor unit?

An indoor unit is a pre plumbed (easy for your Plumber to install) which also houses your hot water tank. This comes in white panels and look like a fridge. (Insert link to photo)

Where does the indoor unit go?

Where does the indoor unit go?

The indoor unit can be located anywhere within your house. This is in place of your conventional copper cylinder in your hot press. It is designed to look like a tall fridge and will blend in nicely with kitchen units or utility units. 

Where does the outdoor unit go?

Where does the outdoor unit go?

The outdoor unit can be located anywhere outside your building. However, it is best practice to keep it as close to the building if possible. This will reduce the length of gas pipes that will be needed to run.

What is Part L?

What is Part L?

Part L is one of many Building Regulations that your house will have to meet on completion. Part L relates to heating and hot water. This is a very detailed document that your Builder, Plumber, Heating Designer will have to follow to meet the minimum requirements and to make sure your heating system is up to building regulations. 

The Part L document of current building regulations sets out maximum energy usage and carbon emission levels for the dwellings. It also states that all new buildings must incorporate some form of renewable energy technology to help reduce the use of fossil fuels to heat the dwelling or to reduce the primary electricity usage. The most popular renewable energy sources used are heat pumps for heating and hot water. 

How does underfloor heating work?

How does underfloor heating work?

Underfloor Heating consists of a lot of water pipes under your floor. Your heating source (boiler or heat pump) will heat this water in these pipes which in turn will heat your floor to a nice uniformed comfortable. The warm floor will heat your room.

What is Underfloor Heating

What can go wrong?

What can go wrong?

There are many components in a heating system. There are also many different quality components. When poor quality components are used, this when things can go wrong. While most of the components can be replaced easily as these are accessible, what is not easily accessible is the pipes under your floor. There has been lots of horror stories in the industry that have not got to the public domain with regard to substandard pipe. Stories that included, people having to move out of their house to accommodate removal off all floors in the house to replace pipes that have failed after a number of years. The pipes began to leak after a number of years, only for the homeowner to find out that the warranty of the pipes has expired, and they would incur the very expensive cost. Insurance companies will not cover costs on uncertified pipe. 

There are a few things to look out for to avoid horror stories outlined above. Ultimately, insist on full design insurance, high quality components with long warranties so that you will not incur costs in the event of any issues that may arise. As the pipe will be fitted within your floor structure, you should insist on a 50-year warranty on the pipe. Do not take the word of a Seles Rep, please insist on documented evidence.

What warranties do Pipelife have?

How can some suppliers offer a cheaper alternative heat pump heating system to Pipelife?

How can some suppliers offer a cheaper alternative heat pump heating system to Pipelife?

Generally, there are some competitors that can offer cheaper comparisons. This is only done by compromising on something. Whether it be quality, quantity or service. There are lots of ways of reducing the price offered. The most common trick is reducing the quantity of components. For example, the quantity of pipe and controls. We would suggest you ask all potential suppliers for a detailed list of quantities, on every quotation. Remember, your heating system should last for many years, you need to know exactly what you are getting. Study and compare all quotations. Make sure that the quantities of all the components are the same. One item less may affect the price but it will also effect the running costs of your system as well as the level of comfort in your house. Insist on warranties of 50 years on the pipe and at least 5 years on all other components.

Another trick that is used widely is reducing the size of the heat pump. An under sized heat pump will cause nothing but problems in the future. An under sized heat pump will have to work harder all year round resulting in expensive running costs as well as burn out. Burn out consists of the heat pump burning out and require replacing same. This is a very expensive and avoidable exercise. It has been found, that under sizing a heat pump will result in burn out between 4 to 6 years. Just when your warranty has expired. Leaving you with an unexpected very large expense.  

How do we Buy your system?

How do we Buy your system?

All systems and components can be purchased through your local hardware shop giving the peace of mind that you are buying locally. We can also offer a fully designed & installed system either through your local plumber or one of our partners throughout the country. Pipelife have Certified Installers throughout the country and we would be more than happy to you in contact.

What features make Hitachi Air-to-water heat pumps so energy efficient?

What features make Hitachi Air-to-water heat pumps so energy efficient?

Hitachi was one of the first manufacturers to use DC inverter technology for heat pumps This keeps temperature fluctuations to a minimum, giving customers the opportunity to tailor the temperature of their homes to their own preference, whilst saving up to 40% of energy compared to systems without this technology.

Which Hitachi heat pump do I need?

Which Hitachi heat pump do I need?

It depends on many factors, including the size of your flat or house, the type and number of heating elements involved and hot water function. Your living environment also plays an important role. In general, you can use both Yutaki M and Yutaki S in connection with common radiators or underfloor heating systems. The Yutaki S heat pump is a split system, consisting of an outdoor unit and a separate indoor unit. In contrast, the Yutaki M heat pump is a compact solution, whereby only a single unit has to be installed on the outside. It does not take up much space and can use an existing heating solution. Your Hitachi specialist dealer will be happy to help youmake the right decision.

Can I heat and regulate temperature

Can I heat and regulate Temperature

No problem with the Yutaki S! The Yutaki S is a split system comprising an outdoor unit and a separate indoor unit. They are connected via a refrigerant pipe and are installed by a trained professional. All sizes are equipped with an electric heater as standard, which can be switched on as needed. This is particularly beneficial in transitional periods. The use of convectors as a heating system means that the Yutaki S can be used to regulate indoor temperatures in summer. It is especially suited to new builds that you ideally want to equip with underfloor heating. Its screed drying function is a real advantage here, which shortens the drying process considerably. It also has a legionella purge cycle, automatic summer cut-off (this does not affect service water heating) and the option of solar connection.Thus, its use can be customised all year-round.
