This is heavily dependent on the quality of installation, the way the appliance has been used over the years and the quality of maintenance and care it has received.
Help & FAQs
Noise will generally only occur when the unit heats during the night or when requested by you during the day. The unit contains a copper cylinder holding 100 – 200 litres of water, which will make some noise when heated, in the same manner a kettle makes considerable noise when heating a far lower quantity of water.
Some noise is therefore unavoidable, however, if the noise level increases noticeably or you are concerned it is excessive, please do not hesitate to contact us.
It is virtually impossible that your PulsaCoil appliance can create high bills, providing it has been correctly installed. Unless you physically press your ‘boost’ button to charge the unit during daytime hours, your unit will only heat on the off peak period and you should be able to identify this cost clearly on your electricity bill.
Most people will notice a significant difference in their electricity usage during the summer months when they do not make use of electric radiators. High electricity bills are far more likely to be linked to your domestic appliances or heating system.
While this high temperature guarantees safe water quality, we do understand that this temperature is very hot. Older people who have more sensitive skin, may have restricted movement and be unable to react quickly. They are consequently more vulnerable to scalding, especially if ‘stuck’ in a bath or shower.
The temperature of the hot water cannot be ‘turned down’ via our appliance due to the risk of bacterial build up within your pipework, but it can be reduced at the outlet itself through the installation of a thermostatic control.
We are delighted to be able to offer a range of thermostatically controlled products which will control and significantly reduce the temperature of water you use for showering, bathing, and hand washing.
These products conform to the highest British safety standards and mix the hot and cold supplies to a pre- determined safe temperature, consequently allowing a far more comfortable water temperature and significantly reducing the risk of scalding in the home.

Your PulsaCoil appliance is designed to meet with Building and Water Authority Regulations, which stipulates that hot water is routinely delivered to tap outlets at no less than 50°C
These temperatures prevent the growth of micro-organisms within your pipe work and eliminate the risk of legionella and harmful bacteria within your hot water. You can therefore have absolute confidence that the hot water that you use to bathe and wash with is completely safe.
The hot water delivered through your taps is your mains cold water which has been instantaneously heated by our appliance. This means that the hot water produced is the same quality as your incoming mains supply and should therefore be of drinking quality.
You have no exposure to stored water and there is nothing our unit can do to influence the quality of your water. The PulsaCoil eliminates the risk of legionella or dangerous bacterial growth affecting your hot water supply.
When you initially turn on the hot tap, you draw the water that has been stood in the pipework between the PulsaCoil and the tap itself. It is not until this water is drawn off that you then receive the hot water that is generated by the PulsaCoil. This is unavoidable and would be experienced with ANY boiler.
You may experience a fluctuation in temperature of the water for a further 20-30 seconds. This is just the unit adjusting the output temperature to the taps as it passes the sensor on the unit.
We advise that if you are away from the property for less than 2-3 weeks, then leave all power switches on. If, however, you are going away for longer than 3 weeks, you can make a small saving by turning your OFF PEAK SUPPLY OFF, but leaving the MAIN POWER SUPPLY ON. This will stop the unit heating up on the off-peak periods, but the pump is exercised on a regular basis – reducing any potential problems on your return.
Inside your appliance a store of water is held within a copper cylinder, which will cool if the appliance is switched off. If the water held in the copper cylinder is allowed to remain cool for a prolonged period of time, the natural rate of corrosion of the copper cylinder will accelerate and the lifetime of your appliance can be significantly reduced. If all the power is turned off, the pump is not exercised on a regular basis and has an increased likelihood of seizing up.
We would not therefore recommend leaving your unit switched off for several months without the appliance being drained. Gledhill Response would be pleased to drain your unit for you at a subsidised rate should this ever be necessary.
Turning the appliance off during the daytime will not save electricity. Since the unit only charges overnight, unless you are on an Economy 10 tariff or actually request a top up of hot water (by pressing your ‘boost’ button) you will not use a significant amount of electricity during the day.
Turning off your unit overnight will not save money since the temperature of the water held in the store will fall and a similar or greater amount of electricity will be used when the unit is turned back on to restore the water temperature.
