Question

Heating btu required........question


I am getting all kinds of results from online calculators on btu needs of my room.


I am building a 400 square foot room in middle Kansas and I am trying to dertermine the btu`s that I need to heat it.

It will be 2 by 6 walls with r-19 and a r-38 cieling.

Any help would be appreciated,I will be using hydronic baseboard heating.

A space heater would work best.

I think a 420 W [give or take] space heater will do it, at least in Topeka, with its 5100 HDD.

Heating btu required........question


Thanks guys....I am south of Topeka and it`s slightly warmer there in the winter.


I think I will go with the hydronic baseboard heat in about a 500/1000 watt hi low range and about a 9000 btu a/c unit ,wall mount...the patc was what i was looking at ,but i dont like the fact if one part goes out I loose everything while i am down for repairs.


It`s about 200 bucks for the baseboard hydronic heater and about 300 for a decent thru the wall 9000 btu a/c,with a thermostat in about a 11 eer.


I would go with patc......but its about 650 for a decent one and they have a heat pump with electric back up and a/c ,but the heat is way more than I need and I am not shure about everthing in one unit deals.......

I appreciate all the help.


On a side note ...lol at some of the online calculators ...they were giving numbers like 10,000 to 26,000 btu for that little room ,a few of them that were more reasonable were giving around 7000 ,which is closer to what I thought it might need.I knew the 20,000 btu figures were way overboard.

I think I will be plenty safe with 5000 btu......I hope.

Just a rule of thumb 500 sqft per ton

I'm sure I'm going to get flamed for saying that because a load calculation would be best. Again just a general rule of thumb.

I'd still go for 12k for cooling and 3k for heating.


I'm just a little west of you in Hays.

Yep, about 45 minutes north...I am outside of Rozel.

I think those are the numbers I will use.....it gets hot as hadies in the summer and it will not hurt to have plenty of cooling

I just bought 5.5 acres there and I am moving from california to Rozel....considering the average year round tempature is 70 here...I want plenty of heat and cooling there.......


Thanks for all the help.
