Adjusting Apollo hot water tank

I am not sure what you are asking, But i am going to assume that you want to know about changing the Temp on the heater for inside the house.
If the floor heat was installed properly than it should have a temperture manifold or adjustable thermostat for seperate heating.
You need to find the thermostat or manifold for the garage heat and set it at what ever temp you want the garage to stay at.
Then you can change the A B C knob to a higher setting A is cold B is warm ac is hot. So Increase your temp setting on the heater and this will increase your house water temp for hotter showers and faucet temps. However, they recommend not setting the temp above 120 degrees to prevent severe burns.
If you have a newer home increasing the Hot water heater temp setting may not change the temp at the shower or faucets if you have scald guard faucets installed in the house. This will require adjusting the scald guard valves on each faucet.
I recommend using a candy thermometer or digital thermometer to check the faucet and shower Temp prior to using them and make sure that you inform everyone in the house after you change the temp so that no one gets scalded.
I hope this answers you question, feel free to contact me if you need more help!

pull the housing off the spindel.
turn the spindel anti clock wise.the more you turn the lower the temperature.
refit housing
turn shower on and test

more info is required if this does not solve the issue

My water is not hot

There are two access panels on the heater, remove screws to access it. They cover the upper thermostat and element and the bottom covers the bottom thermostat and element.
The top thermostat is the main one that has a reset button along with a dial to turn up the heat for the top element. A white plastic knob that you can use a flat head screw driver to turn to adjust.
Also you have one on the bottom to turn to adjust the heat on the bottom.

This is how you adjust thermostat's to increase to a hotter setting.

The temperature in my shower is very luke warm only at the shower

Do you mean the other faucets in the house are hot and only the shower is warm? If so there is an anti-scald adjustment on the faucet that needs to be turned up a few notches. Havent adjusted a Grohe faucet but most faucets you rmove the handle and behind the handle is a nothced adjustment ring that prevents the faucet from getting too hot. This ring, or stop, is pulled out and twisted clockwise(or counter clockwise to set higher or lower max temp, then pushed back. maybe you can look up grohe to see which way ring or stop adjusts for hotter water.
