What is a Conservatory?

What is a Conservatory

A conservatory is like a miniature greenhouse attached to a house. Conservatories have glass or plastic walls and roofs to let in sunshine. They provide pretty views of the outdoors without bugs or bad weather. But when it’s cold out, heat escapes fast through all that glass. Without good heating, conservatories turn into icy boxes! No one wants that. So it’s key to keep them warm and cosy when it’s chilly.

Why Heat a Conservatory?

There are some great reasons to add heat to your conservatory:

  • You expand your living space. Heating means you use the room year-round, like gaining an extra family room.
  • You enjoy outdoor views and nature comfortingly from indoors. Watch birds at the feeder with your feet up while protected from the cold.
  • A warm, working conservatory adds value to your house. Heat makes it more usable for you or future owners.

Picking the right heater for all that glass is important.

What To Think About Before Buying a Heater

Consider these things before getting a heating system:

  • How big is the space? Bigger conservatories need more powerful heat.
  • Is it well insulated? Uninsulated rooms lose more heat.
  • What’s your budget? Fancy heaters cost more than basic ones.
  • What noise level is OK? Some heaters hum more than others.
  • What look do you want? Wall or ceiling units or underfloor pipes?
  • Can you connect the system to existing house heat?
  • How handy are you with tools for installing heaters?

Measure your conservatory’s size and windows. Is it draughty? What can you afford for comfort? Ask these questions before picking a heater.

Extra Heating Tips

Extra Heating Tips

Along with your main heater, these additions really help:


Install insulation under floors, behind radiators and around windows. Less heat escapes insulated rooms. Costs drop when holding heat.

Use Curtains

Close heavy curtains and blinds at night. Keep daytime sun shining in, close at sunset to insulate windows. Curtains complement heating systems beautifully. Open when sunny, close when dark.

Only Heat When Needed

Don’t heat unused rooms! Setback smart thermostats to lower temps when not occupied. Why heat an empty space? Programmable controls maximise savings big time.

What’s the cheapest way to heat a sunroom?

Portable electric heaters are most affordable for conservatories. Basic models start around $100. Great supplemental heat and money savers!

What heating method works best long-term?

Though pricier to install, underfloor systems provide efficient, even warmth for years in conservatories. Overall cost savings eventually offset initial expenses.

Should my sunroom have double pane windows?

Yes, upgrading to double or triple insulating glass panes is smart despite higher cost. Better insulation pays off through much lower heating bills over time.

How can I spend less on heating such a glassy space?

Strategies like added insulation, thermal curtains, timed thermostats, and secondary glazing on windows combine to cut heating costs majorly. Every bit of heat retained counts!

How warm should my conservatory be in winter?

For happy plants, 50-65°F works, even down to 40°F for hardy varieties. But for cosy human use, conservatories should stay closer to 68-72°F during colder months.
