Had a Panasonic heatpump installed yesterday, just in time for the cold snap. This morning car showed 7.5c outside and indoor thermometer showed 15c. Turned on the heatpump set to heat 21c... It took a long time for the fan to start working - as in five to six minutes. 

 

Not having had one before: does it take some time to heat up before it starts the fan? And how long are temperature changes via IR control activated (as in the heatpump will check temperature every 30 seconds, every minute, every five minutes, etc)?

Also, I'm sure @timmmay will know more about this...

Our heatpumps are Toshibas, yes it can take a while for the heat pump system to start up. Ours take a couple of minutes but not 5-6 minutes.

I have a Daikin and a Fujitsu. Typically it takes no more than 2-3 minutes to start producing significant quantities of heat after being turned on. Being cold at the moment maybe a bit longer, but 5-6 minutes seems high.

 

On both my heat pumps, once you change the target temperature it reacts within seconds. If it's on 19 and I turn it up to 23 I will hear the fan in the indoor unit turn up almost immediately.

We have 2 Panasonic units that look very similar (same model range) - but are different capicities.

 

The smaller (lower power) one starts very quickly - within a few seconds.

 

The heavy duty one can sit for several minutes appearing to be doing nothing - Though the outside compressor unit starts up straight away - just the inside bit doing nothing. Then away it goes.

Should have gone gas.... from cold start to warming in 45seconds....

Yes, sounds like the one I have here...

We have a ~9kW Daikin unit at our batch that takes ages to get going, I haven't timed it but it's got to be around 5 minutes.

Our 6kwh Mitsi usually power's up within 1 minute but occasionally, especially when it hasn't been used in a while, it does take a good 5 minutes to get going. Once its going though it runs rampant. Tech told us at last service its completely normal.

We have a huge ceiling mounted Fujistu.  Yes in can take a few minutes before roaring into life.  My bet is it's entirely normal.

Ok, sounds like this one is working fine... After some minutes of nothing it came like crazy (setting the fan to max) - changed to auto and it slowed down a bit and seems to be working as intended...

That reminds me of something I read...

 

--

 

There once was a man who loved puns. One day while reading the newspaper he saw that they were running a pun contest with a huge cash prize. The man was very excited as he had collected many puns over the years and would love to see his favorite pun run in the local news paper. For days he reviewed his pun list to pick his 10 best puns to send in. When the day of the announcement came he was sure that one of his amazing puns would take the prize. 

However, to his great disappointment, no pun in ten did.

A wait when starting from cold or switching modes is entirely normal.

 

 

 

The outside unit has to spin up and start extracting heat (or dumping heat) out of/into the air and transferring that to the refrigerant gas and depending on the run length of the pipe work and capacity of the system, that can take a while.

 

 

 

There is nothing stopping the indoor unit from starting immediately, but all it would do is move the air inside your room around. Until the external unit has gotten up to speed and has actually changed the temperature of the refrigerant (either heating or cooling it), the internal unit can't do anything meaningful.

 

 

 

Some internal units do start moving a little air immediately to get a better idea of the temperature of the room, but as a general rule, they won't spool up their fan speed until the system is actually ready to heat or cool.

Got a large Panasonic one also - from a cold start it will take several minutes before really putting out heat - I think the outdoor unit has a compressor heater or something similar that needs to warm up for a few minutes first.

Doesn't sound too unusual, the heat exchanger can take a few minutes to start up. I have a (third party add-on) WiFi controller that lets me start it up when I'm still some way from home so the house will be warm when I get there, if I turned it on when I got in the door it'd still take awhile to get warm air into the room.

I expect most new heat pumps have a decent timer built into them, particularly one the BFG would buy, but if not Broadlink make cheap and not too crappy IR remote controls that work with most heat pumps.
