How Many Tent Heaters for a 20×40?

One $100 heater takes the edge off a 20×20. A 20×40 dinner in September usually wants two. A 20×60 wants two or three plus walls.

01Two for a 20×40 dinner

A 20×40 is 800 sq ft. One $100 heater takes the edge off a cocktail hour. A seated September dinner usually wants two heaters and at least the windward sidewall ($50).

20×20: one. 20×60: two or three. Heaters without walls heat the neighbourhood.

Key Takeaways
  • 20×40 dinner → two heaters ($200/day).
  • Walls $50/day keep the BTU inside.
  • Not in the Covered package.

July afternoons rarely need them. The minute the sun drops behind a Surrey treeline, the canvas goes cold. Read heated tents for fall weddings.

05Field notes from the warehouse

800 sq ft. One $100 heater takes the edge off cocktail hour. A seated September dinner usually wants two ($200/day) and the windward sidewall ($50). 20×20: one. 20×60: two or three. Heaters without walls heat 192 Street.

May and September are the heater months. July afternoons are not. Sunset behind a Surrey treeline changes the canvas in 20 minutes — read heated tents for fall weddings.

Two heaters $200/day + wall $50 = $250 on top of the $1,100 20×40. Not in Covered $1,236. 25% deposit. We install them with the tent; you do not pick up 80-lb heaters in a sedan.

Fuel/operation is part of the rental conversation on the quote — we do not strand you with a cold box and a manual.

One heater 'to try' on a 20×40 dinner is a warm head table and a cold dance floor. Budget two.

Do not bring patio mushrooms from Costco into our marquee without telling us. Placement and clearance matter.

A real hold, not a “from” price: two heaters + windward wall for a 20×40 September dinner is $250.00 CAD before tax on the published list. Twenty-five percent is $62.50 in RentKit the day you book. Balance $187.50 before the crew rolls from 9317 188 St, Surrey. Marquee frames stay on our truck — they are not a warehouse pickup. Delivery starts at $175, quoted to the pin so Vancouver and Harrison are not a 7 AM surprise.
