NEC Section 424.3(A) Branch Circuit Requirements. ....Branch circuits supplying two or more outlets for fixed electric space-heating shall be rated not more than 30 amperes....
NEC 424.3(B)Branch circuit sizing. Fixed...shall be considered continuous load.
Continuous load means load no more than 80% of circuit rating, so a 20A circuit can't be more than ...

Provision power for heaters with a 125% derate
You need to study the unit's specs carefully, and note the amps or VA drawn by it (note a resistive electric heating element will have VA identical to Watts, but a fan motor may knock that off a little). Then, multiply that figure ...

I had that exact problem at the house I previously lived in. It started when the water company installed meters & check valves. Before then, any expansion in the water heater would simply push a bit of water back into the distribution system. After the installation of the check valves, the water heater pop-off valve would even release a bit of hot ...

If you get a burst of water flow which seems like an over-pressure, it may be time to replace the pressure reducing valve in the water supply line.I would put a pressure gauge on the cold water. Then run the water for a few seconds until the pressure stabilizes in the line. Stop running water and see if the pressure gauge rises as I suspect it will. You can ...

If you’re hearing the noise when the fan kicks on, it could be that too restrictive a filter is installed.

Absolutely! Most motion sensors are IR (infrared) detectors and they can "see" heated air as it moves. If it moves fast enough it may trick the sensor into thinking that it's a human vs. just heated air. In your case the heater may be hitting the sensor directly with its IR output.
Try redirecting your sensor so that it doesn't pick up heated air output ...

I had the whistle in my last home ,, actually in my shop , the corrugated flex whistled when it was at full blast.
Last try for tonight connect or ? Problems.
I upsized from 3/4 to 1” flex and the whistle was gone, it’s the flow and the ripples that make the whistle, upsize the flex 1 size you double the area and noise gone, ok last time .
ok this worked ...

It's unlikely that going from a larger pipe to a smaller pipe (which is essentially what the flex hose is) would cause that. However, the repair man may have meant that the flex hose was undersized for the gas line inside the furnace, which would make more sense. Expanding flow could certainly cause the noise, but to really figure out what's causing it you'...

According to Qlima website, the heater is equipped with oxygen depletion sensors (ODS). These sensors can tell how much oxygen is left in the air. If the oxygen level decreases then this activates the sensor and the gas shuts off to the logs.

What you want is possible, but requires an extra box
While button-type (electronic) countdown timers that can switch 240V directly aren't a thing due to the limited market they would have; this is still possible provided neutral is available to the timer and you are OK with an extra box hanging around. In particular, what you can do is use a suitable timer ...

With the limited info provided I will guess that it is a 240v heater as the other one was but this time they only used a single pole thermostat to control the power, it works the negative here is that there will always be a hot conductor in the baseboard unless the breaker is turned off, this used to be quite common, or was used with multiple heaters in 1 ...
