Low-grade and latent heat into a municipal network

Reading order

Name the heat object before you name a dwelling count. Write whether the file is sensible heat in an air or liquid loop, latent heat stored in a phase change, or a flange temperature the municipal network will actually buy. A 30 °C hall loop is a loop temperature. A 68 °C Avropsvärme sentence is a supply-line temperature. They are not the same cell. The parent page already owns prepared, letter of intent, contract and delivered. This page keeps the physics cells named.

Then name the product, not a generic “district heat.” The May 2023 sheet writes Avropsvärme with a 10 °C outdoor call-off guarantee, Prima with a 68 to 103 °C band, Inblandning with 68 to 80 °C all year, and Retur with a plus-3 °C return lift. A return-line product is a lower-temperature door. It is still a sensible-heat flange. It is not a latent-heat tariff. Exergi’s FAQ writes that yesterday’s 16:00 publication sets the next day’s price, temperature and call-off. A day-ahead publication is not a twenty-year offtake.

Only then open the lift and the Swedish legal door. Exergi’s Conapto sentence writes heat pumps from about 30 °C to 70 °C. That lift is how a low-grade sensible loop becomes a named flange. Latent heat — energy bound in evaporation or condensation — is a different physics cell. Evaporative rejection puts energy into water vapour. The discharge-permits page already owns that water file. Energimyndigheten’s data-centre page describes Article 26.6 of Directive (EU) 2023/1791 as a proposed amendment to the cost-benefit-analysis law for centres with a total energy supply above 1 megawatt. The July 2025 Government Offices memorandum is that proposal. It is not an in-force Swedish latent-heat duty on this page.

• Name loop temperature, flange product or latent phase-change before any dwelling count.
• Keep Avropsvärme 68 °C off a 30 °C hall loop.
• A 16:00 day-ahead print is not a twenty-year contract.
• The offtake page already owns the District Heating Act file.

What a low-grade or latent claim actually is

A municipal network buys a named temperature at a named flange. The May 2023 sheet writes that Avropsvärme suits halls and other activities with a surplus that is even across the day and the year. That is a load-shape sentence. It is not a latent-heat definition. Prima, Inblandning and Retur are three other load-shape and temperature doors. Retur is the lowest published lift: at least 3 °C above the incoming return. A hall that cannot reach 68 °C still has to name which product, if any, the counterpart will discuss.

A heat pump is the usual lift between a ~30 °C loop and a ~68 to 70 °C flange in the Conapto sentence. That sentence is Exergi’s description of one operator’s first plant, with a first-plant dwelling illustration of about 2,500 homes. A dwelling illustration is not a measured annual megawatt-hour on this page. The FAQ’s indicative 2 million kronor for 1 megawatt delivered most of the year is likewise labelled indicative. It is not a Swedish statutory tariff and not a Falun or Falkenberg invoice.

Latent heat stays a physics cell. Evaporative cooling and two-phase rejection move energy as a phase change. Recovering that energy for a municipal network still ends at a sensible flange the network can accept. The discharge-permits page and Folkhälsomyndigheten’s cooling-tower page already own the water and health-protection doors. This page will not invent a Swedish product called latent heat, and it will not treat water vapour as a sold megawatt.

The legal door is still a proposal where this register has sourced it. Energimyndigheten’s data-centre page points to a proposed amendment tied to Article 26.6 for centres above 1 megawatt total energy supply. The July 2025 memorandum proposes a cost-benefit analysis and, where that analysis shows technical and economic feasibility, a duty to use waste heat or take other recovery measures. A memorandum is not an in-force duty. The reporting page already owns the 500 kilowatt filing duty from 1 July 2025. A filing duty is not a flange temperature.

What named primary sources show

The May 2023 Open District Heating sheet shows the four products, the normal 68 °C Avropsvärme supply temperature, the 10 °C outdoor call-off guarantee, the 68–103 °C Prima band, the 68–80 °C Inblandning band and the plus-3 °C return lift. The FAQ shows the 16:00 day-ahead publication, the 6-to-9-month technical sentence, the indicative 1 megawatt / about 2 million kronor sentence and the “more than 20” reference-plant sentence.

Exergi’s data-hall page shows the 2021 Conapto contract, the about-30-to-70 °C heat-pump lift and the about-2,500-dwelling first-plant illustration. Energimyndigheten’s data-centre page and the July 2025 memorandum show Article 26.6 as a proposed Swedish cost-benefit and recovery duty above 1 megawatt total energy supply. The District Heating Act and Ei’s district-heating pages remain the contract file on the offtake page.

Related pages already in this register: heat-reuse four states, district-heating reuse, offtake contracts, discharge permits and energy-performance reporting. GleSYS’s 1 October 2020 Falkenberg start remains a dated delivery start. It is not a latent-heat product.

A matrix instead of one latent tariff

The table is a permission table. A filled cell is a claim the named URL can carry. An empty cell means this page will not invent a Swedish latent-heat product or a hall invoice.

Do not treat a 30 °C loop as a 68 °C flange, and do not treat an indicative 2 million kronor as a statutory tariff.

Common misreads

The first misread is to treat a 30 °C loop as a sold municipal megawatt. The Conapto sentence writes a heat pump to about 70 °C. The second is to treat Avropsvärme’s normal 68 °C as every Swedish network’s flange. The sheet is Stockholm Exergi’s product. The third is to treat water vapour from evaporative rejection as a latent-heat offtake. That energy is still a water and health-protection file until a counterpart names a flange.

The fourth is to treat the indicative 2 million kronor as a statutory tariff or a Falun invoice. The fifth is to treat the 6-to-9-month technical sentence as a Swedish hall permit. The sixth is to treat Article 26.6 as an in-force Swedish duty. The sourced Swedish papers still call it a proposal.

What to ask next

If a brief prints a Swedish latent-heat tariff, ask which named URL uses that sentence for a loop temperature, a named Exergi product, a return-line lift or a proposed Article 26.6 duty. If the URL only shows a dwelling illustration or an indicative krona, the brief has already left the source.

Then open the parent heat-reuse page, the offtake-contracts page and the discharge-permits page. Those pages already own the commercial states, the District Heating Act file and the evaporative water door. This page only asks whether the physics cells stay named.

1. Is the file a loop temperature, a flange product or a latent phase-change claim?
2. Which Exergi product is named — Avropsvärme, Prima, Inblandning or Retur?
3. Has a 30 °C loop been treated as a 68 °C sale?
4. Has the indicative 2 million kronor been treated as a statute?
5. Has Article 26.6 been treated as in force?

What this does and does not prove

This page proves that Stockholm Exergi already publishes named flange temperatures and that a ~30 °C hall loop is written as needing a heat-pump lift before those flanges. It proves that Article 26.6 is still sourced as a Swedish proposal.

It does not prove a national latent-heat tariff. It does not invent a measured Falun megawatt-hour. It does not treat water vapour as a sold product.

Empty cells stay empty. Until a later primary source names a Swedish hall’s flange with a dated product and a boundary, the heat stays a method, not a census.
