About the Heta Inspire 45

The Heta Inspire 45 is a modern 5kW stove and is manufactured in Denmark. The stove is very solid (thick steel) and has an excellent efficiency rating (84%). Customers particularly like the clean lines and high efficiency.

We did not choose this stove as is usually the case - this stove was chosen by our customers. We added the Heta Inspire to our site following a particularly high demand for quotes for the stove from our customers, despite the fact that it was not on our website - this being a sure sign that a stove is a potential winner :-)

The Heta 45 is amongst our best selling stoves (Winter 2019) and was third most searched for stove when we look at our search statistics.

Customers have a knack of sniffing out the best stoves and are certainly pointing other customers towards the Heta Inspire 45.

Body and door

Steel stove (5-year body guarantee) with steel door.

What to buy steel or cast-iron? Do not overthink. Steel heats fast. Cast-iron takes a little longer but retains heat longer as fire dies.


This stove can, if sited outside of a fireplace recess, be sited on a 12mm thick hearth.

If in a fireplace recess, a full 125mm thickness constructional hearth is required. This will usually be in place as part of the recess design.

Hearth regulation advice here

Distance to combustibles SIDE: 300mm
Distance to combustibles REAR: 195mm (145mm log store version)

To non-combustibles there are no hard rules but, around the stove, a 50mm minimum air gap is recommended to brick/stone. This to be increased to 100mm for rendered or boarded surfaces. Prior to purchasing any stove download the installation manual to check that manufacturers do not have any additional requirements.

  • Gift/Discount
  • Delivery promise (14 days to report any damage)
  • Exceptional six-months guarantee (even if stove used)
  • Price match
Buying online is a little disconcerting for some. What if I get a lemon? What if I'm happy when I unwrap it?
If your stove's retail price is under £1300: Should you not be happy with your stove for any reason, within the first three months from purchase, we will arrange to have the stove collected from your premises (we pay first £48 delivery collection cost, covers most UK postcodes, you pay additional in rare situation cost rises above £48 for any reason). Stove installed and has been used? No worry. We will pay you up to £100 to have it removed by a Hetas registered installer.
As soon as the stove is back with us we will provide a FULL REFUND of the cost of the stove. We will even post you a pallet and straps as required (you will need to prepare it ready for our driver). This exceptional guarantee lasts for a full three months from date of delivery EVEN IF THE STOVE IS USED as long as normal wear and tear.
Between three and six months, we offer exactly the same but without the £100 stove-removal offer.
On this, you have my word.

Heta inspire 45

So easy to use stovefitters warehouse site to do the research and make the purchase. Julian's team also supplied a fitting pack with all that I needed with no further running around. Having fitted a woodburner before I can say the liner and stove pipe are great quality. The burner has simple clean lines and burns great, and well made. Very pleased

Hetas inspire 45 5 kw

I bought the hetas inspire 45 from Stovefitters Warehouse for a very good price. It looks fantastic but what sets it apart from the last stove I had is its efficiency. I can’t believe how much heat is produced from a few small pieces of wood and how long they last in the stove. The controls are easy to use and lighting the stove is no problem at all. I give this stove 10/10
