The unit is an on the wall combi boiler. It does the hot water when you turn on the taps and also the wall radiators when the heating is switched on. It takes up the same space as a single cupboard unit on the wall. THIS WAS FITTED INTO A SMALL KITCHIEN with water filtration system aswell. You need to get the kitchien fitters, heating engineers and water filter guys all in the same room at the same time to check all the pipes meet up and fit together!!!!!!!!!!!!!
The pipes are in a double loop to the first and second floor with a master mains in the kitchien and upstairs bathroom. The pipes are run in the floor and wall but are insulated with 20mm foam covers.
The brand is Valiant and they fitted the unit and vent which they cut a hole in the wall to fit. Radiators are wall mounted with thermostate control valves so you can adjust the heat from 0-5.
The unit is controled by a single wireless remote that can work on temperature or timer. The wall unit has a control fpor the water tap temperature and the temperature for the water in the radiators.
Cost for the Valiant Bolier and 7 radiators 43K rmb installed. I had to haggle for the wireless remote to be included for free, usual cost 1000rmb extra!!! This is for a split level apartment of 3 bedrooms, two bathrooms and Living/dinning room. Aprox 145 square meters. |

Great information, sounds like they did a good job for you - not easy to come bye in China!
Sounds like 2 single supply loops, not a supply and return (2 pipe) system. |

We have an apartement with fully floor heating and I never ever want to miss it again.
To find it was a matter of luck though (housing allowance is not that big). When we were looking for a new apartement we checked out +/- 30 apartements and there was only ours with floor heating and another one with very small radiators on the wall (I think they were heated with warm water from the kitchen boiler)
I don't think that a bathroom floor heating will have any effect on the rest of the apartement.
The problem are the windows and walls -> no isolation
Last winter we had to run our floor heating 24/7 on around 26 degrees to get a room temperature of around 20 degrees. It takes around 2 days until the flat is warm.
The gas bills for these month were huge though. But since we don't use air con in summer it's okay for us. |

After live almost 4 years in One Park Avenue, I can not stand the "cold" inside my apartment and bought a brand new apartment with floor heating 2 months ago. I plan to live there from this winter but unfortunately, my company offer me a good position in Thailand last week. I will visit Thailand in 2wks and if I decide to move to Thailand, my apartment will be available for rent. It location is so close to German or American or Singaporean international schools - just before A9 entrance. If you are interested, pls let me know. My friend, who just move there told me that she need to turn on the floor heater for 2 hours ONLY and it will last for at least 12 hours. I would like to lease it for US$1,000/month for 3 bedrooms 2 bathrooms 180SQM+20SQM balcony - but no furniture or basic only. |

Reviving a thread here but...
To those that renovated their house, was drywall and insulation ever considered??
Just wondering? Till I came here many years ago, I lived in Canada and in-floor heating never caught on so much. The walls/ceilings/floors are insulated and the windows are double pane, storm sealed. Seemed like more than enough!
My first winter here, i felt like MacGyver, trying to seal the windows, and doors and installing ceiling fans to push the hot air down. Worked like a charm.
We are buying an apartment here next year and my plans are to try to keep the heat in, not necessarily HOW I’m going to heat.
Some things to add (if applicable)– Keep heaters underneath windows if you can. Good insulation is as, if not more important than the heater used. Use radiators and a few well placed 12” fans or even better, ceiling fans, to move the air around. Save your split mount A/Cs (my god, totally useless!!!) for summer. Weather strip your doors. Keep inside doors closed. Put towels on your window panes.
About ten years ago, I had a small three car garage that was totally concrete; walls and floors. The ceiling was bare beam. I converted it to a recording studio. It was insulated with 1 ½” Styrofoam. One 500 watt base board heater in the control room and three in the live room kept the rooms/as warm as needed, even in the dead of a Canadian February! |

About sealing.. I think the first priority should be to seal the balcony door of the living room (assuming it's a common style apartment) which has the biggest size compared to windows of other rooms..
By the way, where did you buy the seals? Is the brand/model important, or are they just standard? |

BUY!!!!!!!!!!! MacGyver doesn't buy, he improvises!!!!
Actually when i came to shanghai, i didn't know squat about the availability of products. So i went in search of plastic. I found thick plastic used to cover heavy traffic carpet areas. I think "carpet runner" is its name. I bought some electrical tape as well and basically taped the plastic to the window frame. At that time i had the oh so common green window frame you can see on half the buildings in Shanghai, so bought green electrical tape:). The point is the thickness of the plastic doesn't matter - what matters is that you prevent air from moving through the window! you could essentially use painters plastic and it would do the same thing.
About ten minutes after i completed the job, my heater which was on constantly(not lying), turned off for the first time!
A few days later i found my century mart had a "home mart" i believe is the name. In there i found some door seal. i put that on...at first the door was almost impossible to close but try and try again, it too worked. Suddenly my front room was a little warmer...
In fact i've never been to a B&Q so i don't know what you can find there. I've driven past 'em and they are big so give it a try, but don't be afraid to improvise. point is - prevent air from moving through windows and doors. If you are worried about fresh air...and no kidding - buy lots plants!!! As if the air in Shanghai is clean anyway! |

We moved out of One Park Avenue because of the cold in the winter (and the generally soul-less hotel like feel of the apartment). 3 things that helped us
1. Get a "hotu carpeto", they have them at hola. Is basically a carpet with a heating mat underneath, similar concept to an electric blanket. It doesn't get amazingly hot, but it's so nice to sit on when the rest of the apartment is cold. Note: Hotu Carpeto is the pigdin Japanese name for them, not sure what they're called in Chinese, but like I said, Hola has them.
2. Get a thick curtain made for the window/balcony door in the living room. Glass is so thin that I could fart in the kitchen and you could smell it on the balcony, with the door closed.
3. We took a pile of empty moving boxes, cut them up, and duct taped them to the bedroom windows. Doesn't look pretty, but if you close the curtains, you can't see them anyway, and we rarely open the bedroom curtains.
other than above, and buying a floor heater/blower thing for the bathroom floor, there's not much you can do. Oh, and closing all the doors to the rooms you don't use, but you probably don't need me to tell you that. |
