💚💚Maximising the efficiency and running costs of your Heat Pump.💚💚

Heat pumps can be an efficient and cost effective way to heat you home, below are some tips and tricks to maximise the performance of your heating system, and explanations on the technology can be especially useful for recent adopters of the technology.

😬 Manage Expectations and hold fast! – The kW output and efficiency of air source heat pumps varies with the outside air temperature. Above 15C you can expect a Coefficient of Performance (COP) of 4/4.5, this means you put 1kWh of electricity in, you get 4/4.5 kWh of heat out, worst case is when temperatures are between +2 and -2C, at this point any moisture in the air freezes onto the heat exchanger and the system has to integrate a defrost cycle, this brings the COP down to 2.5, past -2 and all the way to -15/20 efficiency increases again slightly as defrost cycles are not often required because air humidity drops. The figure which is most important is Seasonal Coefficient of Performance (SCOP) this is the efficiency of the system over a year and takes into account the highs and lows, here we can expect 3-3.5, anything above 3 is when systems become cheaper to run than gas boilers. So in short, super cheap to run most of the time, but expensive to run some of the time, overall it will be cheaper. Unfortunately, most people do not know how much gas and oil they use each day, the energy companies spread usage out over the year which gives a false impression of actual winter heating consumption. Being electric, and the fact most people have smart meters, you can see exactly how much the system has used every day instantly. What often happens is people will see a reading from a particularly cold day, lets say £15 in electric and immediately work out that it will cost thousands or pounds a year to run at that cost per day. There will be some days that the system costs a lot to run, but those are made up by the days its costs a lot less to run, hold fast and see what the system has actually cost to run in a year, don’t fixate on the bad days.

😡 The curse of energy price rises – Mrs Miggins has a heat pump fitted in the summer, energy prices shoot up just before winter, she sees the heat pump running at its most inefficient time and works out how much it cost to run that month, then compares it with the monthly gas direct debit she paid last year, there is a big difference. As per the previous paragraph, you have to take an annual calculation on the running cost of the heat pump, and if you are going to compare it with the running costs of the previous system, you need to compare consumption over the year also, but with adjustments to how much you would have paid on the new gas prices. Only then can you get an accurate comparison.

⚡ Are you on the best electricity tariff? - Often people who have gas heating systems previously focussed on getting the best rates on gas, because that’s where the majority of the bill was allocated. The focus should be getting the best rates on electricity, some suppliers like Octopus even offer special rates for heat pump owners. With the cost of daily standing charges going up, can you have your gas meter removed?

💻 Take advantage of smart tariffs – With the advent of smart meters, suppliers can offer very flexible rates with significantly lower price at certain times. Using the control programmes on the heat pump allows you to take advantage of these tariffs, if for example you have enough hot water storage in the cylinder to last a day, programme the heat pump to heat the cylinder at off peak times only and if you have a tariff with several low periods in a day you can alter the thermostat temperatures accordingly.

💡 Heat Pumps are not Gas/Oil boilers – We set them up to heat properties differently, high and low temps rather than off and on, feeding the heat in little and often rather than a massive dump of heat twice a day. If the normal set temperature is 21C, we would suggest dropping it by 3-4 degrees in the off period, so 17/18C, but give the system an hour at least to get the property back up to temperature. The result is more consistent air temperatures throughout the property, less cold spots and ultimately overall running costs of an average of about 10-15% less than a gas boiler.

🤔 Will the house stay warm with cooler radiators? The lower the flow temperature of the water going round the radiators, the cheaper a heat pump will be to run. Often people get obsessed with radiators being hot, when the most important factor is room temperature, if the room is warm enough its irrelevant whether the radiators are hot. So it could be possible to turn down the flow temperature by 2-5 degrees and still maintain, room temperature. This will often mean that the outside unit has to run for longer to maintain the temperature, but overall the running cost will be less. It’s better to have it running low and slow, rather than fast and hot!

👍 Is the system commissioned properly? A heat pump uses a complex control system designed to maximise efficiency and offer versatility, there are lots of parameters which can be altered, if not done correctly it will adversely affect performance. Weather compensation, heat curves, legionella cycles, pump speeds… All have to be programmed to suit the heating and hot water systems specific to that property.

🥶 Installation and Insulation – Heat pumps are fitted outside, they need a free supply of air to operate, any restrictions to air flow can cause the unit to recycle the cold air it has produced, make sure nothing has been placed around the unit which could restrict flow. Additionally, as they are fitted outside, are all the pipes leading to the unit, properly lagged to prevent heat loss, this includes any pipework running through lofts, but not installed under the loft insulation.

😁 Keep it Serviced - There is often a perception that heat pumps do not need an annual service, this is incorrect. Aside from it being a requirement of manufacturer warranty and RHI/BUS grants, a service can improve efficiency by maintaining effective water and air flow and give the engineer the opportunity to check system settings and tweak performance accordingly.
