Asking for a friend. Their house is heat exchanger/solar only, so electric only. They would like the bath water to be hotter than it is.
Is this possible to do?
They’ve asked me to say that it’s underfloor heated, no rads.
@Little_Lord_Fauntleroy your time has come
I’m no expert but shouldn’t you have some form of a tank to store/heat the water that feeds the rads and the taps? My understanding is that at least once a week this need to heat the water to a certain temp to kill off bacteria like legionnaires etc so surely there should be a way to program it to up the normal hot water temp
If your home uses solar electricity and a heat exchanger to heat water, here are some steps to increase the temperature of your bath water:
- Check Solar System Efficiency Sunlight Availability: Ensure there is enough sunlight during the day to generate the required energy. If it’s winter or cloudy, your system may not be producing enough electricity. Solar Panel Maintenance: Clean the solar panels to remove dirt or debris that might reduce efficiency. 2. Inspect the Heat Exchanger Thermostat Settings: Check if the thermostat on your heat exchanger is set to the desired temperature. You may need to increase it slightly. Scale Buildup: Limescale buildup in the heat exchanger can reduce efficiency. Descale it if necessary. Pump Performance: Ensure the pump in the system is circulating water effectively. 3. Supplement with Backup Heating Many solar systems are paired with electric immersion heaters or other backup systems for times when solar power is insufficient. Activate the Backup Heater: Turn on the immersion heater or backup heating source to raise the water temperature. 4. Optimize Water Usage Preheat Water: Run hot water in other taps to get rid of cooler water sitting in the pipes before filling the bath. Insulate Pipes and Tanks: Ensure that hot water pipes and storage tanks are properly insulated to minimize heat loss. 5. Adjust Usage During Peak Solar Hours Schedule baths during the late afternoon or evening after the solar system has had time to fully heat the water. 6. Upgrade Components if Necessary Larger Hot Water Tank: Consider upgrading to a tank with better insulation or a larger capacity to store more hot water. Additional Panels: Add more solar panels to increase energy generation if demand consistently exceeds supply.
If you’re still experiencing issues, consult a professional to assess the system’s performance and make adjustments or repairs.

Is it solar pv and then heating the exchange or solr solar thermal?
I don’t know tbh.
Is it a heat pump were talking about?
Pretty certain you can change the water temperature on the heat pump programmer.

This; heat pump unit is in the hotpress should have a menu to allow you to set the water temperature.
It is. There is a daikin heat pump and there’s solar panels as well
Just want a properly hot bath or shower
Does the panels feed heat directly to the hit water cylinder? Or is it providing electricity to run it?
If you have a heat pump whats the make? Ive a mitsubishi can send you some set up info
Daikin is the heat pump.
Fair enough ive no idea, all i did was type the make and model into youtube and watched a few set up videos
@flattythehurdler which one does your pals panels look like?
Solar PV

No bother, say research the boiler on YouTube to set up. The solar thermal can give issues if not installed correctly, i would have pointed your pal in the direction of someone who fixes solar thermal issues
Yes. Somewhere in the Daikin controls there will something called tank temp or Hot Water temp and it sounds like it’s set too low (maybe 45 degrees). This could be bumped to 55. Careful of scalding too though when using first.
Your friend will never settle into Galway if he’s properly washed

@Little_Lord_Fauntleroy if it’s cold out and I burn rubbish in front of my heat exchanger so the air is warm coming in is that Green?
