- Preparation: usually within 24 to 48 working hours after payment.
- Transit: about 7 to 9 working days after the carrier collects, depending on region and stock. Weekends and bank holidays do not count.
- Shipping costs: appliances £35.99 incl. VAT, or free from £350 of appliances. Firewood and pellets use pallet rates and are never free. Delivery policy.
- Tracking: emailed when the carrier takes the goods.
Returns and refunds
- Cooling-off: 14 days under UK distance-selling rules. We also take unused, resaleable returns up to 45 days. Details on the Returns page.

Frequently asked questions about this product
Central heating use, pellet storage, servicing, installation, and delivery for pellet boilers.
Do you install this stove?
We do not install stoves or flue systems ourselves. Perth Stove Centre Ltd supplies the appliance and arranges carriage to your address. A qualified installer registered with HETAS (or an equivalent competent-person scheme) must fit the stove, connect the flue, and certify the work against Building Regulations Part J where that applies in your area.
We can confirm external dimensions, shipping weight, and the nominal heat output from the manufacturer datasheet so your fitter can check room size and liner diameter before you commit. Smoke Control Area authorisation, planning constraints, and grants that need an installer's invoice sit outside this online sale. Most buyers order the stove here and book the fitter once a delivery week is known.
How does stove delivery work at home?
Orders on this site leave our UK warehouse for the delivery address you enter at checkout. Deliveries outside the United Kingdom need an email agreement before payment, because carrier rules differ. Palletised stoves and inserts are handed over at kerbside or the nearest firm ground the HGV can reach. The driver does not carry units upstairs, through narrow hallways, or across soft ground without prior arrangement.
Before you pay, compare the pallet weight and crate size on this page with your doorway, path, and any steps. If access is tight, tell us when you order. When the goods arrive, inspect the packaging while the driver is still there. If the crate is crushed, torn, or clearly mishandled, write dated reservations on the delivery note (not a vague "subject to unpacking" line), take photographs, and email [email protected] within 48 hours with your order number so we can open a carrier claim.
Who sells and ships this product?
The seller is Perth Stove Centre Ltd, a company registered in Perth, Perth and Kinross, Scotland. We trade as a specialist hearth and solid-fuel retailer: we hold stock, prepare orders, and ship the reference shown on this page. We are not a marketplace listing other people's inventory. Registered office, company number, and contractual terms are in our legal notice.
You buy on thestovecentre.com, pay by card before dispatch, and we deliver to the mainland UK address on your order confirmation. No walk-in counter, no depot collection, and no cash or card payment to the driver. Sizing, lead times, or access questions before checkout: [email protected].
Is the product new?
What you see here is normally current manufacturer stock, supplied new and in the maker's factory packaging when the factory still provides one. Ex-display, end-of-line, or refurbished lines are uncommon on this catalogue; when they do appear, the product page states that in plain words in the description.
Your statutory rights under the Consumer Rights Act 2015 apply if the goods arrive faulty or not as described. Keep the email confirmation and invoice. Where the manufacturer publishes a warranty for this reference, that warranty sits alongside for eligible parts under the maker's own registration rules and time limits.
How do you explain the displayed price?
The catalogue mixes stoves, inserts, flue parts, and accessories from manufacturer end-of-line batches and scheduled stock rotations. The goods stay new; when the factory ships retail packaging, that is what arrives on the pallet.
Carriage for qualifying appliances is £35.99 including VAT, or free when the appliance subtotal in your basket reaches £350. Kiln-dried firewood, pellets, and other fuel lines never count toward that threshold. Checkout shows the exact shipping line before you pay. No shop pickup, and nothing is settled with the carrier at the door.
Can this replace my gas or oil boiler for central heating?
Many pellet boilers are designed to feed radiators or underfloor loops, but only a heating engineer can confirm pipework, buffer tanks, controls, and whether your emitters match the boiler's output band.
Treat this page as the appliance supply. Hydronic design, commissioning, and Building Regulations for the heating system are separate from the online sale.
How much pellet storage and refill work should I expect?
Boilers burn through fuel faster than a small room stove. Plan dry indoor or purpose-built store space for pallets, plus a clear path from store to hopper. Wet pellets jam feeds and cut output.
Hopper or store volume on the datasheet drives how often you fill. Weekly habits are normal on domestic boilers in cold weather; bulk stores stretch that out if the site allows.
What servicing does a pellet boiler need?
Expect regular ash removal and an annual (or maker-specified) service that cleans heat exchangers, checks seals, and verifies safety devices. Skipping service is a common reason for fault codes and poor efficiency on forums.
Manufacturer warranty terms often require documented servicing. Keep invoices. We can point you to the maker's service schedule for this reference when you ask.
