At what temperature do you feel underfloor heating?

[MarkyD]

Here's a link to the manuals and programming guides. LINK The display does have a temp reading. Pressing both the UP and DOWN buttons together for 3 secs takes you to the INFO screens

When I commisioned my screed I did a week of 1 deg rises to 25deg (was at 19deg when started) left it at that for a couple of days then let it cool for a week or two. When finished my controller (Magnum) has a new floor program which gradually increases the temp to working temp over 20 days

You should not run it too hot for extended periods of time and bear in mind that underfloor heating run too hot has been linked (tentatively I'll admit) to problems of DVT particularly in the elderly.

Hi Ajax, what is "DVT" ?

Hi m8, you are doing the right thing. Bring the temp up no more than 5 deg in 24 hrs, when optimum temp reached hold for 2 days. Then reduce temp by no more than 5 deg until cold. This will prevent Thermal shock.

Wilfred - Essentially you are doing the right method as already confirmed.
I'am not aware of the system you have - however they all seem to follow the same principles - gradually increase by small increments over a period of time.
We recently commissioned a Thermonet system in a hallway under unglazed porcelain and ontop of Hardie backer boards and T&G flooring. At 16degees the system still hadn't turned itself on after 2 days so the floor was still warmer at that stage. It was only when we increased the setting to 19degrees that it started to work.
Once you feel the effect of UFH you wonder how you managed before!

Hi guys,
thanks for all the helpful responses but still no joy :mad2:
with my OC2 1991 I pressed the up and down buttons and went into info, then app, then flo, which according to the manual should give me a Reading for floor temp but it just shows the temp I've set it on manual.
I've now had it at 20degrees the last 2-3 hours and still can't feel heat, hate to admit it but maybe it's not working?!
Any ideas? Or anyone familiar with elecktra OC2 1991 controls?
Thank you

Is the room in which the UFH is uncomfortably cold.....

 

[wilfredolimb]

In the mornings it is, especially now weather is cold. You reckon just to not worry about it, there is a towel rail that is ok I suppose

HAve you thought about getting a spark to look at it to see if it is actually working. If it is new - who installed it - can you get them back to sort it? If it is at 20 and still uncomfortably cold it sounds like you might be right and it aint working......

Although thinking about it is the temperature it is reading the room temperature the floor temperature or the core temperature. 20Degrees core temp will give you a surface temp of about 10 to 12 degrees so will still be cold. Is there insulation under the substrate?
