Your Dimplex Heat Pump might not be operating because the external temperature is above the HEAT OFF setting in the advanced settings menu. Also, if the water inlet temperature is lower than 20°C, the inline flow boiler will activate to raise the temperature.
Why my Dimplex LA 6 MI Heat Pump does not heat up enough?
Your Dimplex Heat Pump might not be heating up enough because it is undersized for the heat demand of the property at low external temperatures. It could also be due to the water flow temperature being set too low for the installed heat emitters.
Is ice formation on my Dimplex Heat Pump normal?
Yes, ice formation on the evaporator of your Dimplex Heat Pump is normal during cold weather. The defrost function should keep the majority of the coil clear of ice to allow adequate air flow. Typically, if the ice is less than 1cm thick and the controller does not show a fault, the system is operating correctly.
What to do if Dimplex LA 6 MI Heat Pump does not heat up property quickly?
Dimplex Heat Pumps are designed for continuous operation and do not have a large overload factor to quickly heat a building. To address this, ensure that the property temperature is not allowed to significantly drop during periods of cold weather.
Why is my Dimplex Heat Pump hot water cylinder not hot enough?
The hot water cylinder of your Dimplex Heat Pump may not be hot enough. Check that the coil is correctly sized for the heat pump's output and that the temperature setting within the controller is set to 45C.
How to fix a noisy Dimplex LA 6 MI Heat Pump?
If your Dimplex Heat Pump system is noisy during operation: * Check that the unit is not installed on an incline. * Make sure that all covers are closed correctly.
Why does my Dimplex LA 6 MI Heat Pump emit mist?
Mist emission from your Dimplex Heat Pump is normal during certain atmospheric conditions. This occurs because the drop in air temperature caused by the heat pump is cold enough for mist to form.
What to do if Dimplex Heat Pump hot water cylinder is cold?
If the hot water cylinder of your Dimplex Heat Pump is cold, check that the controller is in TANK mode.
How to fix a blank Dimplex LA 6 MI Heat Pump controller?
If the controller of your Dimplex Heat Pump is blank, check the circuit breaker to the heat pump.
